Medical Terminology

Foundation of Medical Terms

Most medical terms originate from Greek or Latin origins. Some terms are associated with a physician or person who discovered a particular part of the anatomy or a disease.

Prefixes

A prefix is a word part always found at the beginning of a medical term that changes or modifies the word root in the medical term. Prefixes habitually indicate a location, presence or absence, quantity, size, frequency, or position.

Suffixes

Suffix is a word part added to the end of a word to complete that term, usually indicating a procedure, condition, disorder, or disease. Some suffixes are stand-alone nouns that can supplement combining forms for more specificity of a particular term. Suffixes can modification a medical term to an adjective as well.

Word Roots and Combining Forms

A word root most often describes part of the body and sometimes denotes color.

Combining forms are word roots with a vowel added to the end of the word root, making it easier to integrate with suffixes or other word roots. The combining form vowel is often an o; the other two most common vowels seen in combining forms are a and i.

Breaking a Medical Term Apart

To take a medical term apart to define it, (1) start with the suffix, then (2) identify the prefix (if there is one), and, finally, (3) determine the word root(s) or combining form(s).

Understanding the common roots of medical terminology can be incredibly helpful for medical professionals, as well as lay people. Knowing these components and how to combine them makes it easier to decipher unfamiliar words and helps cultivate a better understanding of human anatomy.

For example, “hemat-” means blood, “-ology” is the study of something, so hematology is the study of blood. Similarly, “cyto-” means cell, so cytology is the study of cells. Knowing these terms can give us insight into different medical processes and treatments that we may not have otherwise been aware of.

It’s important to note, however, that many medical terms do not follow this pattern. Some terms have been created to describe specific conditions or treatments, and some are derived from other languages. This means that it’s important to look up words if you don’t understand them. With a bit of research, you can find the source of many medical terms and be well on your way to understanding more complex concepts in medicine. It’s not foolproof; it doesn’t work to just mix and match three components and find a word that is in universal use. For example, “hemi” means half, “narc” means sleep, and “ism” means condition. But if a patient chronically gets half the amount of sleep he should get, he doesn’t have heminarcism!

When it comes to interpreting medical terms, context is key. It’s important to remember that the literal meaning of a term may not be the same as its actual meaning. For instance, the prefix “anti” means against and bio means life, but antibiotics are actually used to kill certain bacteria and other organisms that can cause illness. Knowing this context helps us better understand why certain medications are prescribed and how they should be taken.

Another thing to consider when interpreting medical terms is that words don’t always follow the prefix-root-suffix schema. In some cases, medical terms may include multiple word components, or even come from other languages, so it may be necessary to do additional research to gain a full understanding of the term. Knowing this can provide clues as to what the term means, and give us an idea of how it is used in medical contexts.

Overall, it is important to remember that medical terminology is complex and often requires careful interpretation.

Word roots are the core component of many words. Medical terms usually have one root but can have two or more. Sometimes, when a root attaches to a prefix or suffix, it needs an extra vowel to combine the components. For example, “hem” means blood and “rrhage” means excessive flow. The “o” between the two creates the medical term hemorrhage, meaning excessive blood flow. Not all word roots relate to a body system or a body part, but the following table lists some of the terms that do.

Combining forms are a key component of understanding medical terminology. For example, the word root “cardi” means heart. When combined with the suffix “ology,” which is used to refer to the scientific study or specialty of something, it becomes cardiology which means the study of the heart. The combining form for cardi is “cardio”, which makes it easier to pronounce the full medical term. Similarly, when combining the word root “derm” (meaning skin) with the suffix “ology” we get dermatology or the study of skin. The combining form for derm is “dermo” in this instance. As another example, the word root “gyn” (referring to women) combined with the suffix “ology” becomes gynecology which is the study of women’s health and reproductive systems. The combining form for gyn in this case is “gyno.” A combining form is a word root with a combining vowel. Often, the combining vowel makes the medical term easier to pronounce.

Prefixes are extremely important for medical assistants, as they provide a fast and effective way to understand and describe complicated medical terms. The prefix “anti” means “against” or “preventing,” which can be seen in the word antibiotic, meaning any substance meant to prevent the growth of bacteria. The prefix “hyper” means “above normal,” as seen in the word hypertension, which involves blood pressure higher than what is considered healthy. Other common medical prefixes include “hypo,” meaning below normal; “mono” meaning one; and “multi,” meaning many.

Learning prefixes can help medical assistants quickly identify and remember root words, as well as build their understanding of more complex medical terms. With the right knowledge, medical assistants have the power to understand complicated medical terminology and confidently use their newfound vocabulary in practice.

In addition to prefixes, medical assistants may also encounter suffixes. A suffix is a word ending attached to the end of a root word or stem. An example of a suffix is “ectomy,” meaning removal, as seen in the term splenectomy. Other common medical suffixes include “itis,” which means inflammation; “algia,” meaning pain; and “osis,” meaning a condition or process. When combined with prefixes and root words, suffixes can create even more complex medical terms that describe detailed conditions.

Common General Suffixes

-ectomy: Excision of a body part, usually an organ; for example, tonsillectomy.

-itis: Inflammation; for example, cholecystitis.

-oma: Tumor or mass; for example, lipoma.

Rules for changing from singular to plural

Many medical terms are simply English words that follow standard rules for plural endings. Some just require adding an “s” to the end of the word. Examples are adhesions, lymphocytes, and lacerations. Others that end in “s” or “ch” require adding “es” to the end of the word. Examples are neuroses, viruses, and crutches. For nouns that end in “y” with a consonant in front of the “y,” change the “y” to “i” and add “es.” Examples are colostomies, ovaries, and arteries.

Many medical terms have their origins in other languages, often Latin, so they require a different approach. If they end in “a,” just add an “e” to the end to make it plural. Examples are conjunctivae, vertebrae, and axillae. For words that end in “um,” change the “um” to “a,” like in bacteria, diverticula, and ova. If the words end in “is,” change the “is” to “es.” For example, metastases, diagnoses, and testes. When words end in “us,” change the “us” to “i.” Examples are fungi, villi, and alveoli. Words that end in “on” are made plural by changing the “on” to “a.” For instance, ganglia, protozoa, and spermatozoa. Finally, for words that end in “ix” or “ex,” change the “ix” or “ex” to “ices,” as is the case with appendices, cortices, and cicatrices.

Administrative Medical assistants must have a working knowledge of the medical terms that indicate directions and positions. These terms are used for various types of examinations and diagnostic procedures. Not only do medical assistants need to position patients correctly or optimally, but they also must document how they positioned them and how the patients tolerated any uncomfortable positions.

To help with understanding directional terms, medical assistants should be familiar with the following prefixes and Terms:

Medical Terminology Related to the Musculoskeletal System

Terms used in orthopedic, osteopathic, and chiropractic physician offices will include the names of muscles, bones, and pathologies associated with the musculoskeletal system. Medical assistants in these practice settings will also become familiar with the medications, surgical procedures, and outpatient therapies, or modalities, of the various practices. The modalities employed may be therapeutic devices, such as ultrasound and transcutaneous electrical nerve stimulation, or the application of ice or heat. The medical assistant may be required to administer

Common Musculoskeletal System Diseases and Disorders

There are innumerable diseases and disorders of the musculoskeletal system. In addition to bone fractures, some of the most common diseases and disorders include dislocation, arthritis, osteoporosis, curvature of the spine, torn ligaments and tendons in the knees or shoulders as a result of sports injuries, and injuries to the intervertebral disks of the lower back, affecting the sciatic nerve. Damage to bones, muscles, or tendons and ligaments can result in loss of function to the musculoskeletal system. Treatments are aimed at regaining normal function and controlling pain.

Injuries to Bones

In addition to bone fractures, bone pathologies can include dislocations, various forms of arthritis, osteoporosis, and abnormal curvatures of the spine. The medical assistant can offer information on treatments to reduce pain in chronic bone conditions and safety strategies to prevent bone injuries. Dislocation is the displacement of a bone from its normal articulation. Dislocation is evident upon visual inspection. An x-ray confirms the diagnosis. Treatment for dislocation includes manual repositioning by the physician in the office or, if anesthesia is required, in the operating room.

Scoliosis

Scoliosis is an abnormal lateral curvature of the spine. Scoliosis is more common in adolescents because the adolescent spine is still developing. Symptoms include lateral spinal deformity with back pain. Mild scoliosis generally causes no problems and is usually not noticeable. Severe scoliosis can cause significant back pain and, possibly, heart or lung problems because of the decreased space in the thoracic cavity on one side. Diagnosis is based on a physical examination and radiographic studies. Treatment includes bracing and asymmetrical exercise to correct muscle imbalances where one side is stronger than the other. In severe cases, surgical correction is necessary.

Rheumatoid Arthritis

Rheumatoid arthritis is a chronic systemic inflammation of the joints and synovial membranes that also involves elevated serum rheumatoid factor levels. Researchers believe that rheumatoid arthritis is triggered by an infection in people with an inherited susceptibility to the disease. Symptoms of rheumatoid arthritis include severe joint pain and joint deformity. Diagnostic blood tests for rheumatoid arthritis are rheumatoid factor, antinuclear antibody (ANA) test, and erythrocyte sedimentation rate (ESR). Treatment includes disease-modifying antirheumatic drugs (DMARDs), such as hydroxychloroquine and methotrexate. Immunosuppressive agents, such as cyclosporine and azathioprine, may also be used for treatment.

Some Medical Terms and Their Definitions:

Here are definitions for the medical terms:

Diagnosis: The process of identifying a disease or medical condition by evaluating a patient’s symptoms, medical history, physical examination, and diagnostic tests.
Symptoms: Subjective indications of a disease or medical condition reported by the patient, such as pain, fatigue, or nausea.

A word on STAT

“Routine” orders in medical imaging refer to procedures and tests that are scheduled in a non-urgent manner. These are typically planned in advance and are not immediately necessary to address a life-threatening situation. Routine orders are part of a hospital or healthcare facility’s regular workflow and are scheduled based on the patient’s condition, availability of equipment and staff, and other logistical factors.

On the other hand, “urgent” orders in medical imaging are those that require prompt attention but are not immediately life-threatening. Urgent orders are prioritized to ensure they are performed sooner than routine orders. These may include cases where timely results are important for diagnosis and treatment but do not require immediate intervention. For example, an urgent imaging order might be placed for a patient with abdominal pain to rule out appendicitis.

Finally, “STAT” orders represent the highest level of urgency in medical imaging. These orders are reserved for situations where there is an immediate threat to the patient’s life, and a delay in performing the test or procedure could have severe consequences. STAT orders are given top priority, and all other pending imaging procedures are pushed back to accommodate them. Examples of STAT orders include imaging for suspected stroke, severe trauma, or respiratory distress.

In summary, routine orders are scheduled in a non-urgent manner, urgent orders require prompt attention but are not immediately life-threatening, and STAT orders are reserved for life-threatening situations that demand immediate action. The choice of which category to use depends on the medical condition and the urgency of the situation as determined by the ordering physician.

Introduction to Anatomy and Physiology with Info on Common Diseases

Human body systems are complex and interdependent, each with distinct functions:

Circulatory System: The heart pumps blood, carrying oxygen and nutrients, throughout the body via arteries and veins.
Respiratory System: Lungs exchange oxygen for carbon dioxide during breathing, providing oxygen for cellular processes.
Digestive System: It processes food, breaking it down into nutrients for absorption in the intestines.
Nervous System: The brain and nerves transmit signals to control body functions and respond to stimuli.
Muscular System: Muscles enable movement and support body structure.
Skeletal System: Bones provide structure, protect organs, and produce blood cells.
Immune System: It defends against pathogens and foreign substances.
Endocrine System: Glands release hormones regulating various body functions.
Urinary System: Kidneys filter waste and maintain electrolyte balance.
Reproductive System: It enables reproduction and the perpetuation of the species

Anatomy is the study of the physical structure of the human body. Physiology is the science of the function of cells, tissues, and organs of the body.

Microbiology is the study of all living organisms that are too small to be visible with the naked eye. This includes bacteria, archaea, viruses, fungi, prions, protozoa and algae, collectively known as ‘microbes’. These microbes play key roles in nutrient cycling, biodegradation/biodeterioration, climate change, food spoilage, the cause and control of disease, and biotechnology.

Anatomic Directional Terms

Anatomical directions terms are used universally to describe anatomic structures. Dorsal refers to the back of the body.

Body Cavities and Organs

The body is divided into two main cavities, the anterior and the posterior. These are further divided into the upper thoracic cavity and the lower abdominopelvic cavities. The abdomen can be referred to as having either four or nine regions.

Organs

The body’s organs are made of two or more types of tissue that work together to perform a specific body function. For example, the stomach is constructed with walls of smooth muscle tissue to “churn” the food; it is lined with one type of epithelial tissue, which secretes gastric juices, and covered with another type, which protects the organ; connective tissue fills the spaces between the other tissue fibers; nerve tissue controls the rate at which material is emptied from the stomach. The thymus is part of both the endocrine system and the immune system. The roles of the organs will be discussed in more detail in the remaining chapters of this unit.

Systems

As disclosed in the previous section, organs of the body that perform similar functions are organized into a body system. Again, as an example, the stomach joins with the mouth, throat, esophagus, and small and large intestines to make up the alimentary tract of the digestive system. The small intestine is responsible for the absorption of food into the body. The alimentary tract combines with the teeth, tongue, salivary glands, liver, pancreas, and gallbladder to form the total digestive system. The other body systems, which will be discussed individually, are the integumentary, skeletal, muscular, respiratory, circulatory, urinary, nervous, endocrine, and reproductive systems.

There are numerous diseases that can affect the human body, each with its own set of symptoms. Here are some common diseases and their associated symptoms:

Influenza (Flu): Symptoms include fever, chills, cough, sore throat, fatigue, body aches, and nasal congestion.
Common Cold: Symptoms include runny or stuffy nose, sneezing, sore throat, cough, and mild fatigue.
COVID-19: Symptoms can range from mild to severe and may include fever, cough, shortness of breath, loss of taste or smell, fatigue, and body aches.
Diabetes (Type 2): Symptoms can include excessive thirst, frequent urination, unexplained weight loss, fatigue, and blurred vision.
Hypertension (High Blood Pressure): Often asymptomatic, but severe cases can cause headaches, shortness of breath, chest pain, and nosebleeds.
Asthma: Symptoms include wheezing, coughing, shortness of breath, and chest tightness, often triggered by allergens or irritants.
Arthritis: Symptoms include joint pain, stiffness, swelling, and decreased range of motion.
Heart Disease: Symptoms can include chest pain (angina), shortness of breath, fatigue, irregular heartbeat, and dizziness.
Alzheimer’s Disease: Early symptoms may involve memory loss, confusion, difficulty with familiar tasks, and changes in mood and behavior.
Depression: Symptoms include persistent sadness, loss of interest in activities, changes in sleep and appetite, and feelings of worthlessness.
Anxiety Disorders: Symptoms can include excessive worry, restlessness, fatigue, muscle tension, and panic attacks.
Cancer: Symptoms vary depending on the type and stage but may include unexplained weight loss, lumps or masses, fatigue, and changes in bowel or bladder habits.
Osteoporosis: Often asymptomatic until a fracture occurs, it causes weakened bones and height loss.
Chronic Obstructive Pulmonary Disease (COPD): Symptoms include chronic cough, shortness of breath, wheezing, and excessive mucus production.
HIV/AIDS: Early symptoms can mimic flu-like illness, including fever, fatigue, and swollen lymph nodes. In later stages, it can lead to severe immune system dysfunction.
Stroke: Symptoms may include sudden numbness or weakness, confusion, trouble speaking or understanding, severe headache, and loss of balance.
Hepatitis: Symptoms can range from mild flu-like symptoms to jaundice (yellowing of the skin and eyes) and liver damage.
Migraines: Symptoms include severe headaches often accompanied by nausea, vomiting, and sensitivity to light and sound.
Allergies: Symptoms vary but can include sneezing, runny or stuffy nose, itchy or watery eyes, and skin rashes.
Autoimmune Diseases (e.g., Rheumatoid Arthritis, Lupus): Symptoms depend on the specific disease but often involve joint pain, fatigue, and inflammation.
Ketosis and Ketoacidosis

Ketosis and ketoacidosis are two distinct metabolic states that involve the production and utilization of ketones in the body, but they have different causes, consequences, and implications for health. Here’s an explanation of each:

Ketosis:

Definition: Ketosis is a natural metabolic state where the body produces and uses ketones as an alternative fuel source when there is a shortage of glucose (sugar), which is the body’s primary source of energy.

Causes: Ketosis is typically induced through dietary changes, such as following a low-carbohydrate or ketogenic diet. When carbohydrate intake is reduced significantly, the body’s glycogen stores are depleted, and it begins to break down stored fat for energy, leading to the production of ketones.

Signs and Symptoms: Some people intentionally enter ketosis to burn fat for weight loss. Common signs of ketosis include increased ketone levels in the blood, increased fat burning, and often a decrease in appetite.

Health Implications: Ketosis is generally considered safe for most people when it occurs as a result of dietary choices. It can be a useful state for weight loss and may have potential health benefits, such as improved insulin sensitivity. However, individuals with certain medical conditions, such as type 1 diabetes, should carefully manage ketosis to prevent ketoacidosis.

Ketoacidosis:

Definition: Ketoacidosis is a serious medical condition characterized by dangerously high levels of ketones and acidic substances (ketone bodies) in the blood. It is a medical emergency that requires immediate treatment.

Causes: Ketoacidosis is usually associated with uncontrolled diabetes, particularly in individuals with type 1 diabetes. It can also occur in some cases of type 2 diabetes, though it’s less common. Other triggers can include alcohol abuse, severe illness or infection, and certain medications.

Signs and Symptoms: Ketoacidosis is marked by symptoms such as excessive thirst, frequent urination, nausea, vomiting, abdominal pain, confusion, and fruity-smelling breath. Left untreated, it can lead to severe complications, including coma and death.

Health Implications: Ketoacidosis is a dangerous condition that can quickly become life-threatening. It occurs when there is insufficient insulin to regulate blood sugar levels, leading to the breakdown of fats into ketones, which can lower blood pH and disrupt bodily functions. Immediate medical intervention, including insulin administration and intravenous fluids, is essential to correct the condition.

In summary, ketosis is a natural metabolic state that occurs when the body uses ketones for energy due to reduced carbohydrate intake. It is generally safe and often sought after for specific health goals like weight loss. On the other hand, ketoacidosis is a medical emergency characterized by extremely high ketone levels in the blood, usually resulting from uncontrolled diabetes or other critical medical conditions. Ketoacidosis requires immediate medical attention to prevent severe complications.

These are just a few examples of common diseases and their associated symptoms. It’s important to note that many diseases have overlapping symptoms, and early detection and medical evaluation are essential for accurate diagnosis and treatment. Additionally, individual experiences with these diseases can vary widely.

( A Note About Skin)
The skin is often referred to as the body’s largest organ, and this description emphasizes its significance in the human body. Here’s an explanation of why the skin is considered the largest organ:

Surface Area: The skin covers the entire external surface of the body, forming a protective barrier between the internal organs and the external environment. It’s like a continuous, stretchy, and highly adaptable “sheath” that envelops us from head to toe.
Size and Weight: In terms of sheer size, the skin accounts for a substantial portion of our body’s overall weight. On average, it weighs about 8 to 10 pounds in adults and can represent up to 16% of a person’s total body weight.
Complexity: The skin isn’t just a single layer but consists of multiple layers with different functions. These layers include the epidermis (outermost layer), dermis (middle layer), and subcutaneous tissue (innermost layer). Each of these layers has specific roles, such as protecting against pathogens, regulating body temperature, and housing sensory receptors.
Functions: The skin performs a multitude of vital functions, making it essential for overall health and well-being. Some of these functions include:
- Protection: It acts as a barrier against harmful microorganisms, chemicals, and physical injury.
- Temperature Regulation: The skin helps regulate body temperature through processes like sweating and blood vessel dilation or constriction.
- Sensation: It contains numerous nerve endings that allow us to sense touch, pressure, temperature, and pain.
- Excretion: Small amounts of waste products are eliminated through sweat glands in the skin.
- Vitamin D Synthesis: When exposed to sunlight, the skin plays a role in the synthesis of vitamin D, which is crucial for bone health.
Adaptability: The skin is incredibly adaptable and can stretch, contract, and heal itself to a remarkable extent. This adaptability is especially evident during pregnancy or when people gain or lose weight.

In summary, the skin’s classification as the body’s largest organ underscores its immense importance in safeguarding our health and well-being. It serves as a protective shield, regulates numerous bodily functions, and allows us to interact with the world through sensory perception. Understanding the skin’s significance highlights the need for proper care and protection to maintain overall health and vitality.

Skeletal System (Osteoporosis causes bones to become weak and brittle — so brittle that a fall or even mild stresses such as bending over or coughing can cause a fracture.) MRI very common scan. The medical assistant is responsible for patient instruction prior to the procedure.

Gout caused by build up of uric acid in the joints.

Muscular System

Muscular Dystrophy

In this genetic disease, a group of muscle diseases cause the damage of muscle fiber. There is no specific cure for it and the symptoms include weakness, immobility and imbalance.

Cerebral Palsy

Cerebral palsy is a very common congenital disorder that affects the posture, balance and motor functions. Muscle tone is lost during pregnancy or during child birth. Physical tasks become difficult because of this disorder.

Fibrodysplasia Ossificans Progressiva

In this condition, soft tissue hardens and becomes bone-like permanently. Bone grows between joints and movements get permanently restricted. There is no effective cure available. Only pain management can be done through medication.

Dermatomyositis

In this condition, there is inflammatory myopathy affecting skin and muscle. It is an autoimmune disease harming the connective tissue and weakening the muscles. There is no cure for this condition, but the progression can be controlled by taking corticosteroids and immunosuppressive drugs.

Compartment Syndrome

The blood vessels, muscles and nerves get compressed in a closed area, which ends up in cutting off the oxygen supply. The result is tissue death which can even lead to paralysis. Immediate treatment is the surgery known as fasciotomy. The pressure on muscles will be released after the surgery.

Respiratory System:

Asthma, COPD , Lung Cancer

Circulatory System:

Atherosclerosis and coronary artery disease, Heart Failure, Stroke, High Blood Pressure. Hypertension can cause weakening of the left ventricle of the heart. Contrast media often used in scans of the heart and circulatory system.

Immune System

Immune Deficiency Conditions

SCID (Severe Combined Immunodeficiency)

AIDS

Overactive Immune System

Allergies (caused by either food, drugs, insect stings, or a particular substance)

Anaphylaxis

Asthma

Autoimmune Diseases

Digestive System

Gastroesophageal Reflux Disease (GERD)

Gallstones

Celiac Disease
Crohn’s Disease

Ulcerative Colitis

Irritable Bowel Syndrome

7 Hiatal Hernia when part of the stomach protrudes though the abdomen

8 Colorectal Cancer

Urinary System Nephrosis – a noninflammatory disease of kidneys. Nephrolith – a kidney stone. Urethritis – inflammation of the urethra, the final pathway for urine in both sexes, and the common pathway for urine and semen in the male. Nocturia – frequently getting up and urinating during the night.

Endocrine System

1Hypothyroidism

This is the result of the thyroid gland not putting out enough of the thyroid hormone to keep the body’s functions from slowing down.

Hypoglycemia

Hypoglycemia, as one of the diseases of the endocrine system, is probably best known as low blood sugar and happens when the blood glucose level is below normal. Glucose provides the body with energy and carbohydrates are a major source of glucose. Hypoglycemia usually only happens with diabetics.

Metabolic Disorder

Your metabolism takes the food you ingest and turns it into energy. A disorder happens when the process is disrupted by abnormal chemical reactions. The balance of the nutrients is off and some of your organs can suffer from the imbalance. One example of this disorder is diabetes.

Adrenal Insufficiency (Addison’s Disease)

Addison’s disease, another one of the diseases of the endocrine system, happens when there is not enough of cortisol or aldosterone. These hormones are produced by the adrenal glands.

Cushing’s Disease

This condition is what happens when a pituitary gland produces too many hormones. The end result is an adrenal gland that is overactive.

Diabetes Affects about 9% of the poulation.

Reproductive System Male and Female

Hypospadias – The external urinary meatus (opening) opens anywhere below the tip of the penis rather than at the tip of this disease.

Hydrocele – A fluid-filled sac that partially encircles the testis A swelling on the side of the scrotum is the most common symptom. It’s possible that this will make you uncomfortable. Surgical correction is possible.

It appears as a bulge on the side of the scrotum that resembles a “bag of worms” in appearance and feel. If the condition is causing discomfort, it may be surgically repaired. Due to sluggish blood flow, which raises testicular warmth, this condition might result in a lower sperm count and male infertility.

Cryptorchidism – A condition in which one or both testes do not descend into the scrotum. If not treated before puberty, usually through surgery, it can lead to sterility and an increased risk of testicular cancer.

Benign Prostatic Hypertrophy (BPH) – The prostate gland, which surrounds the base of the male bladder and urethra, swells, producing urination difficulty, dribbling, and nocturia. The scourge of the elderly! As men get older, BPH becomes more common.

Transurethral Resection of the Prostate (TURP) – BPH can be treated surgically. To remove urinary tract obstruction, a device inserted through the penile urethra is used to partially chop away the prostate.

Prostate-Specific Antigen (PSA) – PSA is a protein that can be discovered in prostate cell secretions using a lab test. An increasing PSA level could be a precursor to prostate cancer.

Female Reproductive System Diseases

Endometriosis – A syndrome characterised by the colonisation of the abdominal/pelvic cavity with endometrial tissue islands. The endometrium is the uterine lining that sheds off with each menstruation.

Pelvic Inflammatory Disease (PID)- The female abdominal cavity has a direct anatomical path from the outside world via the female reproductive canal, whereas males have a closed abdominal cavity. Bacteria can travel up the vaginal canal, into the uterus, and into the abdominal cavity via the uterine tubes.

Prolapsed Uterus- The uterus is nearly parallel to the vaginal opening. In fact, the uterus’s cervix, or neck area, reaches into the upper vagina. Ligaments keep the uterus in place so it doesn’t prolapse or herniate into the vaginal canal. The uterine cervix can protrude from the vaginal opening in severe prolapse. To return the uterus to its proper anatomical position, surgery is usually required.

Transmission of a pathogen depends on connecting the following links in the chain of infection.

Infectious agent

Reservoir host

Portal of exit

Mode of transmission

Portal of entry

Susceptible host

What term describes the usual environment of micro-organisms in the human body?

The micro-organisms usually present in the body are the normal flora. Infection can result when the micro-organisms overgrow for various reasons.

What intervention breaks the chain of infection at its first link?

Hand hygiene breaks the chain of infection at its first link: the infectious agent. Killing an infectious agent or removing it from hands interrupts its progression so it cannot reach the second link, the reservoir host.

Effective infection control breaks this chain, thus preventing the cycle from continuing. Hand hygiene breaks the chain at its first link: the infectious agent.

Killing the agent or removing it from hands helps prevent its transmission to the reservoir host, where it would otherwise infect the host and multiply to later infect others. When it gets that far, it has to have a way to exit the reservoir host. Depending on the pathogen, that could be via blood, body fluids, feces, breath, eyes, ears, nose, mouth, or wounds. The means of transmission is either direct (via contact with the infected person or body fluids and secretions) or indirect (via contaminated objects, vectors, and fomites). Indirect transmission is only possible for pathogens that can survive outside of the reservoir host. Once the infectious agent has a portal of entry—a way to get into the body of the susceptible host—infection flourishes.

Conditions for bacterial growth

Many factors contribute to the growth of infections, with environmental factors playing a major role. In general, many pathogens multiply easily in moist, dark conditions. Insects that carry pathogens generally require specific environmental conditions. An example is how standing water in a warm climate “breeds” mosquitoes. Poor food safety and handling also increases the risk of infection, especially when food is not stored at safe temperatures via refrigeration or freezing, or when food processing or restaurant workers do not follow hygienic practices such as handwashing and gloving. Another example is handling feces, such as by health care workers or infant day care center employees. Hand hygiene and gloving are absolutely essential for preventing the transmission of enteral pathogens.

Cellular Division

Cells divide by a process known as mitosis, which results in two new daughter cells. Cells from different types of tissue reproduce at different rates.

Homeostasis

When all tissues and organs of the body are performing their appropriate tasks and the internal environment is functioning properly, the body is said to be in a condition of homeostasis.

Mutations and Traits

Cellular mutation occurs when DNA is lost, rear-ranged, or paired incorrectly during replication. A trait is the recognizable result of a gene or group of genes and can be dominant, recessive, and X-linked.

Genetic and Congenital Disorders

Congenital and genetic disorders result from improper cell division, inheritance of altered genes, environmental factors, and toxins.

Discoveries in Human Genetics & New Techniques

The Human Genome Project analyzed the human genetic structure to determine the location of genes causing disease. Other genetic technologies such as DNA fingerprinting, gene therapy, and genetic engineering have developed.

Stem cell research has great potential as well as great controversy. The government is trying to establish medical, legal, ethical, and moral guidelines.

Lymphatic System

The function of the lymphatic system is to guard against foreign cells, and diseases and provide immunity and fluid balance.

Tissues

Cells combine to form tissues, which join to become organs that function together as systems to form the human body. Blood is a connective tissue. Blood is a specialized type of connective tissue. It is the only fluid connective tissue in the body. Simply, it is a fluid that circulates throughout the human body constantly. It is an opaque fluid with a viscosity greater than water. The mean relative viscosity of blood is around 4.75 at 18 degrees of Celsius.

As you are already conscious, not all cells are alike. They may be transparent, as in the eye, or transmit electrical impulses or nutrients. Some have long, thin fibers, and others produce secretions. When cells of the same type group together for a common purpose, they form a tissue. Tissues are composed of 60 percent to 99 percent water. The essential substances needed by the body are either dissolved or suspended in the tissue fluids. Therefore, water is indispensable to cell life. Lack of it causes death more rapidly than lack of any other substance, excluding oxygen.

Two standard medical terms explain the opposites of tissue fluid balance. When there is too little fluid, the condition is known as dehydration. An abnormal accumulation of excess fluid, causing puffiness of the affected tissues, is known as edema.

Tissue Classifications

Tissues are classified into four main kinds:

Epithelial

Connective

Nerve

Muscle

Epithelial

Epithelial tissues form the body’s glands, cover the body’s surface, and line the cavities. The epithelium is the primary tissue of the skin, which serves as a protective covering for the body. Epithelium also covers all the organs and lines the intestinal, respiratory, and urinary tract, and uterus. Some epithelial tissues secrete fluids, such as mucus and digestive juices. Others selectively absorb nutrients, chemical elements, and water. The epithelium of the urinary bladder is uniquely arranged in folds to allow for expansion as the bladder fills.

Epithelial tissues in glands specialize in providing specific secretions for the body. Glands that secrete directly into the blood in the capillaries are known as endocrine or ductless glands.

Glands that produce secretions through ducts within the body are classified as exocrine. Two glands, the liver and pancreas, produce both endocrine and exocrine secretion

Connective

Connective tissue forms the body’s supporting structure, connecting other tissues to form the organs and body parts. There are three categories of connective tissue: (1). connective tissue proper, (2). consists of water, glucose, fats, and salt and is present in the spaces between the cells of the tissues and within the lymph vessels. Connective tissue plays a significant role in the repair of damaged body tissue. The repair process involves new blood vessel formation and new connective tissue known as scar tissue. Excessive blood vessel development in the early stages may result in a condition called “proud flesh.” In surgery or suturing (sewing) of a clean wound, the need for tissue regrowth and, therefore, the resulting scar are reduced because the cut edges are brought together closely by the surgical process. Excessive growth of scar tissue is called a keloid.

Supportive connective tissue is found in the cartilage and bones of the body. Cartilage is located between the bones of the spine (where it acts as a shock absorber and allows for flexibility) and in the ear, nose, and voice box (to provide shaping). Bone tissue is cartilage with the addition of calcium salts. This addition takes place gradually from birth until the tissue becomes hardened, called skeletal or osseous tissue. It is not a lifeless material. Within most bones is a medullary cavity filled with yellow marrow composed of fat, connective tissue, and blood vessels. Some long bones contain cavities filled with red marrow, which manufactures red blood cells. Because bone is a living tissue with a blood supply and nerves, it can quickly repair itself when it is damaged.

Nerve

Nerve tissue is found throughout the body. It serves as the body’s communication network. The basic structural unit of the tissue is the neuron, which consists of a nerve cell body and fibers that resemble tree branches. The dendrites bring impulses to the cell body; the axon conducts impulses away. Neurons range from a fraction of an inch up to three feet in length.

There are three types of nerve cells or neurons. A sensory neuron in the skin or sense organs picks up a stimulus and sends it toward the spinal cord and brain. An interneuron, or connecting neuron, carries the impulse to another neuron. A motor neuron receives an impulse and sends a message, which causes a reaction.

Clusters of neurons form the nerve tissue. Nerves throughout the body join together to form the spinal cord, which transmits electrical impulses to and from the brain. Nerves outside the brain and spinal cord are called peripheral nerves. Most of the fibers of these nerves are covered with a fatty insulating material called a myelin sheath, which is then covered with a thin membrane called neurilemma. Suppose a sheathed nerve fiber is damaged or cut. In that case, it can be surgically repaired, and a new fiber may form within the sheath, but nerve tissue recovers very slowly. Unfortunately, the brain and spinal cord fibers lack sheaths and cannot be restored by surgery when damaged or cut.

Muscle

Muscle tissue is designed to contract on stimulation. Tissue that can be controlled at will with impulses from the brain is called voluntary muscle tissue. The muscular system receives signals from the nervous system in response to pain. This type is found connected to the body’s bones and is called skeletal or striated muscle. It gives us the ability to move our bodies. Involuntary muscle action occurs without control or conscious awareness. There are two types of involuntary muscle tissue. One type, called smooth muscle tissue, is found within the walls of all the body organs except the heart. This type of tissue moves food and waste material through the digestive tract. It changes the size of the eye’s iris and the diameter of arteries. The other type of involuntary muscle tissue, called cardiac muscle tissue, is found only in the heart. Cardiac muscle fibers are joined in a continuous network. They must contract together in a forceful, rhythmic action to pump blood throughout the body.

Medical administrative assistants play a crucial role in assisting healthcare providers during examinations and procedures in a medical office. Their responsibilities include ensuring the smooth flow of the patient visit and providing support to both patients and providers. Here are ways in which they assist:

Preparation of Examination Rooms: Administrative assistants prepare examination rooms before patient visits. This includes ensuring that the room is clean, well-organized, and equipped with the necessary supplies and instruments for the examination or procedure.
Patient Check-In: They greet patients as they arrive, check them in, and verify their appointment details. Administrative assistants may also help patients complete any required paperwork or update their medical history.
Patient Education: Administrative assistants provide patients with basic information about the examination or procedure, including any special instructions or preparations. They may also distribute educational materials or answer general questions about the process.
Patient Comfort: Ensuring patient comfort is crucial. Administrative assistants help patients feel at ease by addressing their concerns, providing blankets or gowns, and offering support during the process.
Assisting with Medical Equipment: They assist the healthcare provider in setting up and operating medical equipment and instruments. This may include positioning patients for X-rays, EKGs, or other tests.
Documentation: Administrative assistants may be responsible for documenting the patient’s vital signs, chief complaints, or any specific observations made during the examination. Accurate documentation is vital for the patient’s medical record.
Medication and Sample Handling: If required, they assist with medication administration or collect samples for laboratory testing, following proper protocols and ensuring patient safety.
Communication: Administrative assistants act as a liaison between the healthcare provider and the patient, relaying any questions or concerns the patient may have to the provider and explaining the provider’s instructions to the patient.
Maintaining Supplies: They ensure that all medical supplies, disposables, and medications needed for the examination or procedure are readily available and well-stocked.
Post-Examination Assistance: After the examination or procedure, administrative assistants help patients get dressed and ensure they are comfortable. They may schedule follow-up appointments, answer questions about post-procedure care, and provide any necessary educational materials.
Cleaning and Sterilization: Following the examination or procedure, they assist in cleaning and sterilizing equipment and instruments, maintaining a sanitary environment for the next patient.
Appointment Scheduling: Administrative assistants can schedule future appointments or procedures for patients, ensuring they continue to receive the necessary care.
Billing and Insurance: They may assist with billing procedures, including verifying insurance coverage, explaining costs to patients, and facilitating payment collection.
Patient Follow-Up: Administrative assistants may follow up with patients after their examinations or procedures to ensure they are recovering well and address any post-visit concerns.
Adherence to Protocols: They must adhere to medical office policies and procedures, including maintaining patient confidentiality, following infection control protocols, and complying with regulatory requirements.

Overall, medical administrative assistants serve as a vital link in the patient care process, ensuring that patients receive quality care and that healthcare providers can focus on diagnosing and treating medical conditions effectively. Their organizational skills, attention to detail, and compassionate approach contribute significantly to the overall patient experience.

Patient Check In and Check Out

The specific responsibilities of a medical administrative assistant at check-in and check-out may vary depending on the healthcare facility and the specific policies and procedures in place. However, here are common tasks that can typically be performed by the medical administrative assistant at these stages:

Check-In:

Patient Registration: Greet patients as they arrive, obtain their personal and insurance information, and enter it into the electronic health record (EHR) system.
Verify Insurance: Confirm the patient’s insurance coverage, collect insurance cards, and ensure that insurance information is accurate.
Appointment Scheduling: Assist in scheduling or rescheduling appointments, if necessary, and update the appointment book or EHR system accordingly.
Collect Co-Payments: Collect any required co-payments or fees from patients, as per the healthcare facility’s policies.
Medical History: Ask patients to complete or update medical history forms, if necessary.
Provide Information: Answer basic patient questions, provide information about the check-in process, and guide patients to the waiting area.
HIPAA Compliance: Ensure that patient confidentiality (HIPAA compliance) is maintained throughout the check-in process.

Check-Out:

Billing and Payment: Review the patient’s bill, explain charges, and collect any outstanding balances or co-pays. Provide payment receipts if necessary.
Follow-Up Appointments: Schedule any follow-up appointments as directed by the healthcare provider. Provide patients with appointment cards or instructions.
Medical Records Requests: Assist patients in requesting copies of their medical records if needed.
Provide Documentation: Give patients any necessary documentation, such as instructions for medications or post-visit care.
Appointment Reminders: Confirm upcoming appointments with patients and provide reminders, either verbally or through appointment cards.
Insurance Verification: Update insurance information if there have been changes and verify coverage for future appointments, if applicable.
Patient Satisfaction: Ask about the patient’s experience and address any immediate concerns or issues.
Process Referrals: If a referral to a specialist is needed, assist in making the necessary arrangements and provide referral documentation to the patient.
HIPAA Compliance: Continue to ensure patient confidentiality (HIPAA compliance) during the check-out process.

It’s important to note that in larger healthcare facilities, some of these tasks may be divided among several administrative staff members, while in smaller practices, a medical administrative assistant may be responsible for both check-in and check-out procedures. The specific duties can also be influenced by the use of electronic health record (EHR) systems and other technology in the healthcare setting.

It is appropriate to call patients 24 to 48 hr in advance of an appointment to remind them. Calling within this timeframe prevents no-shows and allows for the flexibility to reschedule.

Coordinating laboratory tests and diagnostic imaging

Here is a list of 15 common medical tests for patients along with brief explanations of each:

Complete Blood Count (CBC): A CBC measures various components of the blood, including red blood cells, white blood cells, and platelets. It helps diagnose conditions like anemia, infection, and blood disorders.
Blood Glucose Test: This test measures the level of glucose (sugar) in the blood. It’s commonly used to diagnose and manage diabetes.
Cholesterol Panel: A cholesterol panel assesses levels of LDL (bad) cholesterol, HDL (good) cholesterol, and total cholesterol. It helps evaluate the risk of heart disease.
Blood Pressure Measurement: Blood pressure is a routine check of the force of blood against the walls of arteries. High blood pressure can lead to various health issues, including heart disease and stroke.
Urinalysis: This test examines a urine sample for signs of kidney disease, urinary tract infections, and other health conditions. It assesses elements like glucose, protein, and blood in the urine.
X-Ray: X-rays use radiation to create images of the inside of the body. They’re used to diagnose conditions like fractures, infections, and lung diseases.
Electrocardiogram (ECG or EKG): An ECG records the electrical activity of the heart. It helps diagnose heart rhythm abnormalities and assess heart health.
MRI (Magnetic Resonance Imaging): MRI uses strong magnetic fields and radio waves to create detailed images of the body’s internal structures. It’s useful for diagnosing conditions affecting the brain, joints, and soft tissues.
CT Scan (Computed Tomography): CT scans combine X-rays and computer technology to produce cross-sectional images of the body. They’re valuable for detecting tumors, injuries, and internal bleeding.
Colonoscopy: A colonoscopy involves the insertion of a flexible tube with a camera into the colon to examine the colon’s lining. It’s used for colorectal cancer screening and to investigate digestive issues.
Mammogram: Mammography is a specialized X-ray of the breast tissue. It’s an essential tool for breast cancer screening and early detection.
Pap Smear (Pap Test): This test collects cells from the cervix to screen for cervical cancer and detect precancerous changes.
Bone Density Test (DEXA Scan): DEXA scans measure bone density and are used to diagnose osteoporosis and assess fracture risk.
Thyroid Function Tests: These tests evaluate thyroid gland function by measuring thyroid hormones (TSH, T3, T4). They help diagnose thyroid disorders such as hypothyroidism and hyperthyroidism.
Spirometry: Spirometry assesses lung function by measuring how much air a person can inhale and exhale and how quickly they can do it. It’s used to diagnose and monitor respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD).

An electroencephalogram (EEG) is a medical test that measures and records the electrical activity in the brain. It is a valuable diagnostic tool used to monitor and analyze brain function. Here’s what EEG tests for and how it works:

What an EEG Tests For:

Epilepsy and Seizure Disorders: EEG is most commonly used to diagnose and monitor epilepsy and other seizure disorders. It helps identify abnormal electrical activity in the brain, which can lead to seizures.
Brain Disorders: EEG can detect abnormalities in brain function caused by various conditions, including brain tumors, infections, degenerative diseases (such as Alzheimer’s disease), and traumatic brain injuries.
Sleep Disorders: EEG is used in sleep medicine to diagnose sleep disorders like sleep apnea, narcolepsy, and parasomnias. It records brain activity during different sleep stages.
Encephalopathy: EEG can help diagnose and monitor encephalopathy, a condition characterized by changes in brain function often caused by metabolic or toxic factors.
Monitoring Brain Function During Surgery: In some cases, EEG is used during brain surgery to monitor brain function in real-time and ensure that critical areas of the brain are not damaged during the procedure.

How EEG Works:

During an EEG, electrodes (small metal discs or sensors) are placed on the scalp at various locations. These electrodes are connected to an EEG machine, which records the electrical signals produced by the brain.
The patient is typically asked to sit or lie down in a quiet room with their eyes closed and then open. The EEG records brain activity under different conditions to assess normal patterns and detect abnormalities.
EEG results are displayed as a series of waveforms, which represent the electrical activity of the brain. Normal EEG patterns have characteristic shapes and frequencies associated with different brain states (e.g., awake, asleep).
Abnormal EEG patterns may include spikes, sharp waves, or irregular rhythms, which can indicate the presence of a neurological disorder or abnormal brain function.
EEG findings are interpreted by neurologists or other specialized healthcare professionals who can diagnose conditions based on the patterns observed in the EEG recordings.

EEG is a non-invasive and painless test that provides valuable insights into brain function and can be a crucial tool in diagnosing and managing various neurological and sleep-related disorders.
