1 Medical Terminology


3 Basics Before we can start in with some new and interesting medical terms, you need to learn a few fundamentals of how medical terminology is constructed as a language. There are three basic parts to medical terms: a word root (usually the middle of the word and its central meaning), a prefix (comes at the beginning and usually identifies some subdivision or part of the central meaning), and a suffix (comes at the end and modifies the central meaning as to what or who is interacting with it or what is happening to it). An example may make better sense.

4 Word root therm = heat hypothermia (less heat), thermometer (measuring heat) Let’s look at a real medical term and take it apart. Myocarditis (prefix) (root) (suffix) myo = muscle card = heart itis = inflammation Don’t get blown away by that big, intimidating word! We haven’t introduced word roots yet. I just wanted to demonstrate the major parts of a medical term. Let’s see how prefix and suffix changes can alter the meaning of a term without changing its central meaning by keeping the root the same.

5 Prefix change: myocarditis = muscle layer of heart inflamed pericarditis = outer layer of heart inflamed Endocarditis = inner layer of heart inflamed

6 Suffix change : cardiologist = a physician specializing in the heart cardiomyopathy = damage to heart muscle layer cardiomegaly = enlargement of the heart Again, we haven’t introduced heart terms yet. These basics are just to introduce the parts of medical terms and demonstrate how moving the parts around modifies the central meaning without changing the “root” (cardio).

7 Useful prefixes and suffixes Following, in no particular order, are frequently used word beginnings (prefixes) and word endings (suffixes) used to make up many medical terms. You don’t need to memorize whether an item is a prefix or suffix, or even if it is a word root, just what it means! I know this is all “Greek” to you (and some of it really is!), but there will be so much reinforcement as we go along that you can’t help but remember meanings. Be patient with yourself.

8 -itis = inflammation tonsillitis, appendicitis -osis = abnormal condition cyanosis (of blueness, due to cold or low oxygen) -ectomy = to cut out (remove) appendectomy, tonsillectomy -otomy = to cut into tracheotomy (to cut into the windpipe, temporary opening) -ostomy = to make a “mouth” colostomy (to make a permanent opening in colon) a/an = without, none anemia (literally no blood but means few red cells) micro = small microstomia (abnormally small mouth, see “stomy” in colostomy above?) macro = large macrostomia (abnormally large mouth) Mega/megaly = enlarged megacolon (abnormally large colon = large intestine) -scopy/scopic = to look, observe colonoscopy (look into colon)

9 -graphy/ -graph = recording an image mammography (imaging the breasts) -gram = the image (X-ray) mammogram -ology/ -ologist = study, specialize in cardiologist, nephrologist (study the heart, the kidneys)

10 WORD ROOTS Stomato = mouth stomatitis Dento = teeth dentist Glosso/linguo = tongue glossitis, lingual nerve Gingivo = gums gingivitis Encephalo = brain encephalitis Gastro = stomach gastritis Entero = intestine gastroenteritis Colo = large intestine colitis, megacolon Procto = anus/rectum proctitis, proctologist Hepato = liver hepatitis, hepatomegaly Nephro/rene = kidney nephrosis, renal artery

11 Orchido = testis orchiditis, orchidectomy Oophoro = ovary oophorectomy Hystero/metro =uterus hysterectomy,endometritis Salpingo = uterine tubes hysterosalpingogram Dermo = skin dermatitis Masto/mammo = breast mammography, mastectomy Osteo = bones osteoporosis Cardio = heart electrocardiogram (ECG) Cysto = bladder cystitis Rhino = nose rhinitis (runny nose!) Phlebo/veno = veins phlebitis, phlebotomy Pneumo/pulmo = lung pneumonitis, pulmonologist Hemo/emia = blood hematologist, anemia
