Definition Medical terminology is language that is used to accurately describe the human body and associated components, conditions, processes and procedures in a science-based manner. Some examples are: R.I.C.E., trapezius, and latissimus dorsi. It is to be used in the medical and nursing fields.

Like every other language, medical terminology has changed over time and will continue to change. Most medical terms come from the Greek and Latin languages. 6
importance of the medical terminology Simplify communication/break down the language barrier. Easy understanding(common language) They are specific terminologies, thus makes no need to use general terminology
word elements The medical word contains all or some of these; Word Elements Word root Combining form Suffixes Prefixes E.g. Dermat itis = defined as the inflammation of the skin. Skin(word root) Inflammation(suffix)
Word elements T o n sil lec t o m y ctomy(remove) Tonsil(root) oli g o sper m ia Prefix(Little ) word root suffix(state/conditions) Peri tonsill itis = Inflammation of the tissues surrounding the tonsil Around(prefix) tonsil(Root) inflammation(suffix)
Word root A root is the basic element of a word , and it is the foundation on which the meaning of a word is built. Many roots are real words in their own right and term. Although these roots can have other elements, they don't need other elements to be complete. A root can be a whole word or a part of a word . 10
Word roots All medical terms have at least one word root E.g . of Respiratory system word roots and the meaning Alveol ………. Alveolus(one), Alveoli(many) Bronch……….Bronchus/bronchi Epiglott ………Epiglottis Lob……………..Lobe Nas …………….Nose Or ………………Mouth
Combining forms Combining (Linking ) forms is formed when a word root is combined with a vowel. usually “ o ”, but occasionally “ e ” or “ i ”. i.e Combined form = word root + o 12

Rules! 25 To define medical terms, divide or slash them into their component parts; these word components are called prefixes, suffixes, and roots. Use the hyphen ( - ) after the word component to indicate that it is a prefix; use it after the combining form to indicate that it needs a suffix; use it before the word component to indicate it is a suffix. For example: Epi-gastr/o/-cele
more rules ! 26 Use the combining vowel “o” when a suffix begins with a consonant. i.e Termin/o/logy Use the combining vowel “o” when combining two roots only if the second root begins with a consonant. i.e. Pneum/o/thorax Do not use the combining vowel “o” if you are combining a second root that begins with a vowel or a suffix that begins with a vowel (a, e, i, o, u, and sometimes y). i.e. Pneum/arthr/osis Add –y to a word to indicate a procedure (gastroscopy) or –ly to indicate an act or process (splenomegaly).
And More Rules!! 27 The suffix –osis always denotes a condition (usually abnormal). When combined with the color roots erythr/o- (red) and leuk/o- (white), it represents a condition of abnormally increased blood cells. Most of the time, word components denoting color are used as prefixes. However, sometimes they are the root of the medical term.
