Medical Terminology • Medical terms are made up of parts of words (elements)-prefixes, roots and suffixes. Most originate from Greek or Latin words. • The combination forms our medical terms. • Prefix-a word element placed before the root. Always used with a root! Example olig (scant); oliguria (scant urine) • Root-the word element containing the basic meaning of the word. It can be combined with other roots, prefixes or suffixes. A vowel (o or i) is added when 2 roots or a suffix is added to the root to help with pronunciation (if not one). • Suffix-word element placed after a root. Always used with a root! Nephro (kidney); -itis (inflammation of)
Medical Terminology (cont) • Medical terms are formed by combining the elements. Prefixes are first and suffixes are last. • Examples: • The suffix-ectomy (excision, removal of) is combined with the root-mast (breast) to form mastectomy-removal of the breast. Sometimes 2 suffixes can be used. • The prefix-dys (bad, difficult, abnormal) is combined with the root-pnea (breathing, respiration) to form dyspnea-difficulty breathing. • The prefix-endo (inner, inside) is combined with the root- card (heart), and the suffix- itis (inflammation) to from endocarditis-inflammation of the inner side of the heart.
Medical Terminology Challenge • Determine the medical condition based on the prefix, root (start by deciding main word), and suffix (if present- it comes first) found on pages 72-73 of your textbook. Pair with the most correct answers wins!
