Medical Terminology Basics
When medical professionals document patient information, they use specific formats like SOAP notes (Subjective, Objective, Assessment, and Plan) and record them in an EMR (Electronic Medical Record). Understanding these systems helps you see how medical information is organized.
Medical terms follow patterns with prefixes, roots, and suffixes that give clues to their meanings. For example, the prefix "a-" means "without," as in apoxia (without oxygen), while suffixes like "-al" and "-ic" mean "pertaining to," as seen in pulmonary (pertaining to the lungs). These patterns make learning medical terms easier than memorizing each word individually.
Root words tell you what body part or system is involved. Derm- relates to skin (as in dermatologist), audi/o relates to hearing, and physio refers to natural or physical functions. The suffix -ology means "the study of," which is why gynecology is the study of women's reproductive health.
Pro Tip: When you encounter a new medical term, try breaking it into parts. The prefix comes first, the root is in the middle, and the suffix comes last. This strategy will help you decode thousands of medical terms!

Body Systems and Conditions
Medical terminology helps us describe both normal body functions and what happens when things go wrong. For instance, gastr/o refers to the stomach, while enter/o points to the intestines. When combined with other word parts, they create terms like gastroenteritis (inflammation of the stomach and intestines).
Prefixes can indicate quantity or size. Pan- means "all" (as in pancytopenia, low levels of all blood cells), while micro- means "small" (as in microcephaly, abnormally small head). Hemi- indicates "one half," which explains why hemiparesis means weakness on one side of the body.
Blood-related terms often use the roots hema-, hemat/o, or hem/o. For example, hemophilia is a disorder where blood doesn't clot properly. Similarly, hepat/o relates to the liver, as in hepatitis B (a liver infection).
Remember This: Directional prefixes are super important! Retro- means "backward," while re- means "again." These small word parts can completely change a term's meaning, so pay close attention to them on tests.

Structures and Formations
Medical word endings often indicate what kind of structure you're talking about. Suffixes like -ium, -tic, and -ous refer to structures, tissues, or regions of the body. For example, delirium is a confused mental state affecting brain function.
Problem indicators are important to recognize. The suffix -cele means a swelling, hernia, or tumor, as in bronchocele . Cell-related terms often include -cyte , while quantity prefixes like mono- (one) and poly- (many) help describe numbers.
Body part roots help locate conditions. Acoust/o relates to hearing, somato- refers to the body, and neur/o refers to nerves. Procedure suffixes tell you what's being done: -plasty means surgical reshaping , and -pexy means surgical fixation .
Make This Connection: Many medical terms follow this pattern: quantity + body part + problem. For example, "polycystic" breaks down into poly (many) + cyst + ic (pertaining to). This pattern works for hundreds of medical terms!

Diagnostic Procedures and Conditions
Diagnostic procedures often end with -gram (the record) or -graphy (the process of recording). An echocardiogram uses sound waves to create images of the heart, while electrocardiography is the process of measuring electrical activity in the heart.
Disease-related suffixes help identify specific conditions. The suffix -algia indicates pain , while -itis signals inflammation . When you see -iasis, it typically indicates a condition characterized by or produced by something, as in psoriasis.
Medical specialties often end with -iatric, meaning "healing." Geriatrics focuses on healthcare for elderly patients. Other important suffixes include -lysis (breaking down), as in hemolysis (destruction of red blood cells), and -scope (instrument for observation), like the stethoscope doctors use to listen to your heart and lungs.
Test Tip: For your medical terminology test, focus on the prefixes and suffixes that change a word's meaning the most dramatically. Terms with -itis (inflammation), -ectomy (surgical removal), and -rrhea (flow) are particularly common in healthcare settings.

Surgical Procedures and Conditions
Surgical procedures often contain suffixes that tell you exactly what's being done. -Tomy means cutting or incision, which is why an appendectomy is the surgical removal of the appendix. Similarly, -rrhaphy refers to suturing, as in herniorrhaphy (surgical repair of a hernia).
When looking at discharge-related terms, -rrhea indicates flow or discharge (as in amenorrhea, absence of menstrual periods), while -rrhexis means rupture (as in amniorrhexis, rupture of the amniotic sac). The root py/o relates to pus, so pyogenic means pus-producing.
Structure-related roots give clues about physical characteristics. Scler/o means hard , sten/o refers to narrowing, and semi- indicates half .
Clinical Connection: Healthcare workers use these terms daily to communicate precisely about patient conditions. When a doctor orders an "appendectomy," everyone on the medical team instantly knows exactly what procedure is needed—no lengthy explanations required!

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
