1 HS111 – Medical Terminology Seminar March 30 th – April 5 th, 2011

2 Learning Activities for this week 1. Complete Reading – Ch.2 & Ch.3 2. Participate in Discussion - initial post doesn’t have to be 100 words, but try using at least 5 medical terms; also, initial post has to be by Saturday at 11:59pm EST 3. Participate in Seminar – Opt. 1 or 2 4. Take the Quiz 5. No project due this week

3 Review from last week – intro to word parts * * Don’t forget ** 1. Word root – the word part that is the core of the word 2. Prefix – attached to the beginning of the word root to modify its meaning 3. Suffix – attached to the end of the word root to modify its meaning (most med. terms have a suffix) 4. Combining vowel – a word part, usually an ‘o,’ used to ease pronunciation 5. Defining med.terms – start with suffix, then move to beginning of word ex. Oste/o/pathy – disease of the bone

4 Chapter 2 – Body Structure, Color, and Oncology Organization of the human body o Cell – basic unit of life o Tissues – group of similar cells that perform a specific task o Organs – 2+ kinds of tissues that perform special body functions together o Systems – group of organs working together to perform complex body functions

5 Combining forms of body structure Aden/o – gland Cyt/o – cell Epitheli/o – epithelium Fibr/o – fiber Hist/o – tissue Kary/o – nucleus Lip/o – fat My/o – muscle Neur/o – nerve Organ/o – organ Sarc/o – flesh, connective tissue System/o – system Viscer/o – internal organs

6 More combining forms used with body structure terms Cancer/o or carcin/o – cancer Eti/o – cause (of disease) Gno/o – knowledge Iatr/o – MD, medicine Onc/o – tumor, mass Path/o – disease Somat/o – body Lei/o – smooth Rhabd/o - striated

7 Quiz time – who’s awake!? Tell me what the def’s are: Hist/o - ? My/o - ? Viscer/o - ? Sarc/o - ? Eti/o - ?

8 Combining forms that describe color  Chrom/o – color  Erythro/o – red  Xanth/o – yellow  Chlor/o – green  Cyan/o – blue  Melan/o – black  Leuk/o - white

9 Common suffixes & prefixes Prefixes Dia– = through, complete Dys– = painful or abnormal Hyper– = above, excessive Hypo- = below, deficient Meta– = after, beyond, change Neo- = new Pro- = before Suffixes -al, -ic, -ous = pertaining to -stasis = control, stop, standing -plasia = condition of formation, dvlpmt, growth -osis = abnormal condition -genesis = origin -genic = producing, originating, causing -pathy = disease -plasm = growth -oma = tumor

10 Another quiz! What do these words mean? 1. Fibr/oma 2. My/oma 3. Lip/oma 4. Melan/oma

11 More to that! Cancerous tumor – WR / S Tumor composed of nerve- WR / S Tumor composed of smooth muscle- WR / CV / WR / S

12 Body structure terms  Dysplasia – abnormal development  Erythrocyte- RBC  Histology – study of tissue  Leukocyte – WBC  Carcinogen – substance that causes cancer  Cyanosis – abnormal condition of blue color  Diagnosis – state of complete knowledge (identifying a disease)  Etiology – study of causes (of diseases)  Metastasis – beyond control (transfer of disease from one organ to another)  Oncologist – MD who studies/treats tumors  Pathogenic – producing disease  Prognosis – state of before knowledge (prediction of outcome of the disease)

13 Quiz time! Define the following terms: Histology - ??? Carcinogen - ??? Oncologist - ??? Prognosis - ???

14 Cancer terms Benign – not malignant, nonrecurrent, favorable for recovery Chemotherapy – treatment of cancer with drugs Exacerbation – increase in the severity of a disease or its symptoms Idiopathic – pertaining to disease of unknown origin In vitro – within a glass, observable within a test tube Radiation therapy – treatment of cancer with a radioactive substance, X-ray, or radiation Remission – improvement or absence of signs of the disease
