Medical Terminology Putting together puzzles
2
Elements of Medical Terms
Prefix – beginning of some words Root – foundation of the word that provides its meaning Combining vowel – vowel that joins a root to another root or suffix Combining form – combination of root and combining vowel Suffix – ending of some words
3
Roots foundation of a medical term * Usually Greek or Latin origin
* Constant, unchanging foundation of a medical term * Usually Greek or Latin origin * Nearly all medical terms have one or more roots * Example – Dermatitis * Root – dermat- from the Greek word for skin
4
Combining Vowel Has no meaning of its own Joins a root to another root
Joins a root to a suffix Makes a word easier to pronounce “o” is the most common, followed by “a”
5
Examples… respir-(breathing) -tory -a- Gastr- -o- -enter- -o- -logy
(relating to) -a- Gastr- -o- -enter- -o- -logy (stomach) (intestine) (study of)
6
Combining Forms Combine a root and a combining vowel
Can be attached to another root or combining form Can precede (come before) a suffix
7
Suffixes * A group of letters, positioned at the end of a medical term
* Attaches to the end of a root or combining form * Can have more than one meaning RULES: If a suffix begins with a consonant, add a combining vowel to the root If a suffix starts with a vowel, no combining vowel is needed
8
Different meanings of words by changing suffix
Use of suffixes Different meanings of words by changing suffix Complete Word Combining Form Suffix Meaning of Suffix Meaning of Word Dermatitis Dermat- -itis Inflammation Inflammation of the skin Rhinoplasty Rhin/o- -plasty Surgical repair Surgical repair of the nose Complete Word Combining Form Suffix Meaning of Suffix Meaning of Word Arthroscopy Arthr/o- -scopy Visual exam Visual exam of a joint Arthroplasty -plasty Surgical Repair Repair of a joint

Let’s try it!!!! Each pair has a marker and ‘eraser’ for your desks…
Here are your elements: cardi gastr enter respir -itis logy ectomy logist o a- Your goal is to make as many words as possible, following the rules Underline any combining vowels you used so I can see them!
10
Prefixes *One letter or a group of letters * Precedes a root to give it a different meaning * Can have more than one meeting * Never requires a combining vowel * An occasional medical term can have two prefixes
11
Use of prefixes Different meanings of words by changing prefix

Want a helpful hint?? Prefixes usually indicate:
Quantity, quality, location/position, color Suffixes tend to indicate: Diseases/condtions, procedures, specialties, professions

Plurals and Pronunciations
Plurals – sorry friends, but it’s NOTHING like the English Language. Set up a chart like this one into your notes… Singular Plural Example

Plurals and Pronunciations
Pronunciations – Very important, as one mispronunciation can completely change the meaning of a word. ch sounds like k chondroid (kon-droyd) ps sounds like s psychiatric (si-ki-a-trik) pn sounds like n pneumonia (nu-mo-nya) c sounds like a soft s when it comes before e, i, & y cytoplasm (si-to-plazm) g sounds like j when it comes before e, i, and y generic (jen-er-ik) i sounds like eye when added to the end of a word to make it plural alveoli (al-ve-o-li)
