  1. Dr. Michael P. Gillespie Medical Terminology

  2. Descriptive – descriptive medical terms describes the shape, size, color, function etc. of the anatomical structure. • Eponyms – literally “putting a name upon” - are used to honor someone who first discovered or described an anatomical structure, diagnosed a disease, or developed a medical instrument or procedure. • Eponyms give no useful information about what the item is or where it is located. Categories of Medical Terms

  3. Analyze words by dividing them into component parts. • Do not simply memorize terms. • Break words up into their component parts. • Relate the medical terms to the structure and function of the human body. • The medical terms will be easier to understand if you know their context in health and disease processes. • Be aware of spelling and pronunciation problems. • Some medical terms are pronounced alike, but spelled differently (i.e. ilium and ileum). • Some medical terms are similar and a mispronunciation can lean to a misunderstanding (i.e. urethra and ureter). Objectives

  4. Root – the root is the foundation of the word. All medical words have one or more roots. Prefix – word beginning. Usually identifies some subdivision or part of the central meaning. Suffix – word ending. Modifies the central meaning. Combining vowel – usuallu an “o”. Links the root to a suffix or another root. Combining form – combination of the root plus the combining vowel. Elements of medical terms

  5. 1. Read the meaning of the medical terms from the suffix back to the beginning of the term and across. 2. Drop the combining vowel (usually o) before a suffix beginning with a vowel: gastritis not “gastroitis”. 3. Keep the combining vowel between two roots: gastroenterology, not “gastrentology”. 3 General Rules

  6. Itis = inflammation (tonsillitis, appendicitis, hepatitis) Osis = abnormal condition (cyanosis) Ectomy = to cut out [remove] (appendectomy, tonsillectomy) Otomy = to cut into (tracheotomy) Ostomy = to make a [mouth] (colostomy) A / an = without / none (anemia, areflexia) Common prefixes and suffixes

  7. Micro = small (microscopic) Macro = large (macroscopic) Mega / megaly = enlarged (megacolon, organomegaly) Scopy / scopic = to look / observe (colonoscopy) Graphy / graph = recording an image (mammography) Gram = the image (mammogram) Ology / ologist = study / specialize in (cardiologist, rheumatology) Common prefixes and suffixes
