9 Introduction to Medical Terminology Suqing Wang

10 ORIGIN OF MEDICAL TERMS  Hippocrates was a Greek physician and is known as the “father of medicine.”  75% of medical terms are based on either Greek or Latin words.

11 Basic Elements of a Medical Word 1. Word Root 2. Combining Form 3. Suffix 4. Prefix These four parts of a word are known as ELEMENTS.

12 Word Root Main part or foundation of a word, and basic meaning of a word. All words have at least one word root. A word root may be used alone or combined with other elements to form a complete word. ie: SPEAK (word root) + ER (suffix) = SPEAKER (complete word)

13 The word root usually refers to a body part. Some root words are derived from the Latin or Greek language.

14 Word Root Examples “dent” means tooth “dermat” means skin “cardi” means heart “gastr” means stomach “pancreat” means pancreas

15 cardi - root for heart hepat- root for liver neur - root for nerve nephr - root for kidney cyt- root for cell

16 Combining Forms Correct pronunciation of medical words is important. In order to make the pronunciation of word roots easier, sometimes it is necessary to insert a vowel after the root. The combination of a word root and a vowel is known as a COMBINING FORM.

17 Basic Rules for the Combining Vowel The combining vowel is not used when the suffix begins with a vowel. (neuritis) The combining vowel is used when the suffix begins with a consonant. (neuroplasty)

18 Combining forms consist of a combining vowel. The combining vowel is usually an “o”, but others may be used. ie: gastr / o pronounced GASTRO. Word root Combining vowel

19 When a word has more than one root, a combining vowel is used to link the root to each other. ie: osteoarthritis oste/ o / arthr/ itis Word root Combining vowel Word root suffix Slashes separate elements

20 Word-Building System By understanding the meanings of word roots, one can determine the meaning of complex medical terms by putting together the smaller parts.

21 Leukocytopenia Word Roots: Leuk / (white) cyt / (cell) Combining Vowel / o / Suffix: / penia (decrease)

22 Suffixes A suffix is added to the END of a word root or combining form to modify its meaning. By adding a suffix to the end of a word root, we create a noun or adjective with a different meaning. Often indicates the procedure, condition, disorder, or disease.

23 A combining vowel is used between a word root and a suffix that begins with a consonant (not a vowel). This is to make pronunciation easier. Word root: scler / (hardening) Suffix: / derma (skin) Term: Scler / o / derma (hardening of the skin) Combining vowel

24 Lip: cheil(o), labi(o) Mouth: stom(at), or(o) Sinus: sin Tongue: gloss(o), glott-, lingua- Tooth: odont(o), dent-

25 Brain: encephal(o), cerebr(o) Cheek: bucc(o) Ear: ot(o), auri Eye: ophthalm(o), ocul(o) Forehead: frons Head: cephal(o), capit(o) Nose: rhin(o),nas(o) Neck: trachel(o), cervic(o) Skull: crani(o)

26 Bladder: cyst(o), vesic(o) Kidney: nephr(o), ren(o) Ureter: ureter(o) Urethra: urethr(o) Urine: urin(o)

27 Aorta: aort(o) Artery: arteri(o) Blood: haem(o), sagui(o) Blood Clot: thromb(o) Blood Vessel: angi(o), vas(o) Heart: cardi(o) Vein: phleb(o), ven(o)

28 Abdomen: abdomin(o), lapar(o) Arm: brachi(o) Breast: mast(o), mamm(o) Chest: thorac(o), steth(o) Finger: dactyl(o) Foot: pod(o), ped(o) Hand: chir(o) Rib: pleur(o), cost(o) Toe: dactyl(o) Wrist: carp(o)

29 Ovary: oo(o), oophor(o), ovar(o) Uterine or Fallopian Tube: salping Vagina: colp(o), vagin(o) Womb: hyser(o), metr(o), uter(o)


31 Meanings of certain suffixes -al pertaining to dent/al (pertaining to teeth) -er one who speak/er (one who speaks) -able capable of being playable (capable of being played)

32 -oma (tumor) hematoma (blood tumor) NOTE: The element that comes before a suffix can either be a word root or combining form.

33 The suffixes -scope (instrument to view) -rrhexis (rupture) -rrhea (flow or discharge) all begin with a consonant, therefore a combining vowel must be used between the word root and the suffix.

34 The suffixes -algia (pain) -edema (swelling) -uria (urine, urination) These suffixes begin with a vowel, therefore a combining vowel is NOT used between the word root and the suffix.

35 -itis (inflammation) -ology (the study of) - ectomy (surgical removal) -plast (surgical repair)

36 REVIEW A combining vowel IS used to link one root to another root, and before a suffix that begins with a consonant. A combining vowel IS NOT used before a suffix that begins with a vowel.

37 Prefixes A prefix is a syllable or syllables placed BEFORE a word or word root to alter its meaning or create a new word. Often indicates location, time, or number Hyper- (excessive) Pre- (before) Post- (after) Homo- (same) Hypo- (under) peri- (around) hemi – (half) micro – (large) neo- (new)

48 Plurality To make a medical word plural (more than one), first look at the suffix. Then, choose the rule that changes the singular form to the plural form.

49 These suffixes indicate whether the noun is singular or plural Singular Plural Example SingularPlural aaepatella patellae ax acesthorax throraces eninalumenlumina ix, exices index indices sisses diagnosis diagnoses on aganglion ganglia uma ovumova usi digitusdigiti yies deformitydeformities mamata carcinomacarcinomata

59 Even you has gone through all the studies of medical words forming tricks, you can still get confuse once you get into hospital or conference!

60 Shot You might hear someone say “”Has she had her shots? “ Or “he’s going to need a tetanus shot.”

61 This does not mean that someone will get shot by a gun and badly hurt In the hospital, a shot is medicine that is given through a tiny needle to make you fell better.

62 Dressing You might hear someone say, “He needs a dressing change.” Or “she needs a new dressing.”

63 This does not mean to change clothes. In the hospital, a dressing is a bandage and to change dressings means to put a new bandage on!

64 DYE You might hear some say, “The doctor will inject you with some dye.” Or “the nurse will put dye into you body.”

65 This does not mean the doctors or nurses are going to give you something to make you die. In the hospital, dye ( also called contrast) is given to you to drink or is injected through I.V. so that different parts of your body show up more clearly in pictures that are taken. That way, doctors have a better idea of how to make that part of your body work the way that it should be.
