1. The Language of the Health Profession
MEDICAL TERMINOLOGY
The Language of the Health Profession
Imagine yourself in a foreign country where you do not speak the language. Even simple conversations would be difficult. For example, what if you need
to explain how to sew a dress to someone who does not know what certain words like baste, zipper, and stitch mean? No matter how intelligent you are, you would look pretty silly making sounds and gestures to explain simple sewing procedures.
Each profession has its own language and jargon that makes it difficult for others to fully understand what is being said. (Comic) It is important to realize, however, that this specialized language is needed in order to communicate accurately and concisely. You have chosen to pursue an interest in the medical profession and it is important that you learn to “speak the lingo.”

2. 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.
What’s in a word? The answer is a lot if it is a medical term. Each medical term has a basic word root or stem that usually comes from the Greek or Latin language. In fact 75% percent of medical terms are based on either Greek or Latin words.(Click) The Greeks were the founders of modern medicine, although Latin has become the universal source of medical language. Hippocrates was a Greek physician who lived from 460 to 377 B.C. and whose vital role in medicine is still recognized today. He is called the “Father of Medicine” and is credited with establishing early ethical standards for physicians.
Defining medical terms is a lot like a puzzle. Most medical terms are a combination of two or more word parts or elements. The identification of a word involves a search for the meaning of each of its parts. When they are translated separately and combined into a word, the parts give the essential meaning of the entire word. (Give example- Tonsilitis, Hysterectomy` Osteoarthritis, Cardiomegaly.)

3. ROOT WORDS cardi - root for heart hepat- root for liver
neur - root for nerve
nephr - root for kidney
cyt- root for cell
A root is the foundation or basic meaning of a word.
May appear with a prefix or suffix, or between a prefix or suffix.
The fundamental method of building a medical vocabulary consists of breaking down a word and identifying its elements: prefix, suffix, root or roots, and combining form.
Root (Click)
A root is the foundation, or basic meaning of a word (click) and may appear with a prefix, or a suffix, or between a prefix and suffix. Prefixes and suffixes can never stand alone; they must always be attached to a root. (click) The word root for heart is cardi. However, the term cardi is not normally used by itself. It is commonly combined with another root word, prefix, or suffix to from a complete medical word.

4. PREFIX Pre - prefix means before peri- prefix means around
hemi - prefix means half
macro - prefix means large
neo- prefix means new
The prefix is a part of the word that precedes the word root and changes its meaning.
Often indicates location, time, or number.

7. Combining Forms
Combining form consists of the word root and a connecting vowel to make it easier to pronounce and attach another root word or suffix.
Combining form for heart is cardi
Combining form associated with cells is cyt
(Click) The combining form consists of the word root and a connecting vowel to make it easier to pronounce and atach another root word or suffix
(Click) The combining form for heart is cardi/o
(Click) The combining form associated with cells is cyt/o
(Click) The combining term associated with tissue is hist/o
Once again the terms cyt and hist represent the word roots or foundations. The combining forms can not be put together with prefixes, suffixes, and other root words to produce a multitude of medical terms.

8. 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)
(Click)There are some basic rules which determine when the combining vowel is used and is not used.
(Click) The combining vowel is not used when the suffix begins with a vowel.
Neur/o -nerve
-it is - inflammation
Neuritis - inflammation of nerves or a nerve
