Summary of Basic Medical Terms Glossary

## Introduction Medical terminology is the specialized language used by healthcare professionals to describe the human body, its conditions, procedures, and treatments. Learning these terms helps you read medical records, understand patient instructions, and communicate clearly with clinicians. This guide breaks down common medical prefixes, roots, and suffixes with examples and practical applications. ## How medical words are built Medical terms are often formed from parts: - **Prefix**: at the beginning — modifies meaning (location, number, negation). - **Root (stem)**: core meaning — usually a body part or system. - **Suffix**: at the end — indicates procedure, condition, or specialty. > Example: A word like **colonoscopy** can be broken down into a root and a suffix: colon (large intestine) + -scopy (to look). ### Common prefixes, roots, and suffixes from the list - **Hepat-** (root) = liver. - **Hyster-** (root) = womb/uterus. - **Arthr-** (root) = joint. - **Cephal- / Cephalic** (root/adjective) = head. - **Mega- / Megacolon** (prefix+root) = large, enlarged colon. - **Colo- / Colon-** (root) = large intestine. - **-scopy** = visual examination with a scope (e.g., colonoscopy). - **Cardio- / Cardiologist** = heart / heart specialist. - **Endo- / Endocranium** = inside / inner skull (endocranium refers to inner part of the skull around the brain). - **Anti- / Antidepressant** = against / drug that counteracts depression. - **Laryng- / Laryngoscope** = voice box (larynx) / instrument to view it. - **Decontamination** = removal of contaminating harmful substances. - **Poly- / Polycystic / Polytrauma** = many or multiple (many cysts; many injuries). - **Anti-inflammatory** = against inflammation (reduces inflammation). - **Aseptic** = without infection or contamination. - **Subdermal** = under or below the dermis (skin). - **Micro- / Microscope** = small / instrument to view tiny objects. - **Autoimmune** = self + immune (immune system attacking the body's own cells). - **Spongiform** = sponge-like in shape. - **Hypo- / Hypotension** = low / abnormally low blood pressure. - **Intra- / Intravenous** = inside / within a vein. - **Hyper- / Hyperglycaemia** = high / abnormally high blood glucose levels. > Definition: **Hepatology** — the branch of medicine about the liver and its diseases. ## Terms with short explanations and use-cases 1. **Hepatology**: study and treatment of liver disease.
