Transcript of Medical Terminology

Welcome to the World of Medical Terminology Instructions for Medical Terminology Module

The goals for this section include multiple aspects of medical terminology. Terminology is the foundation of everything you will learn in your training. By performing the exercises herein, you will begin to grasp the basics.
1.Look at the Medical Terminology Presentation.
2.Review Medical Abbreviations in the D2L Glossary.
3.What is "The Do Not Use List." Which organization made these recommendations? Why?
4.Dropbox Assignment:
There are 3 worksheets. Research the words on each worksheet and type in the answers. Once completed, save and submit to your dropbox. These will be graded as an assignment worth 50 points.

5. Take Medical Terminology Quiz when open.

Hint: When opening the worksheets a window will give you the option of open or save, choose save, save in your documents or desktop,fill in with answers, save and then you will be able to attach to the dropbox . This is just the tip of the iceberg This is funny! Crown or circle
Coron/al suture line sits at the crown of the skull
Corona dentis = crown of a tooth
Coron/ary arteries encircle the heart to supply blood to heart muscle.
Coron/ary veins encircle the heart to collect blood from heart muscle. Coron/al
Sagitt/al: A vertical cut made in anteroposterior direction
Mid/sagitt/al: Sagittal cut made at the midline to divide the body into equal right and left halves
Sagittalis = arrowlike. (As if to say if struck with an arrow, a person would be cut into halves.) Sagitt/al 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. REVIEW 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. Suffix 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. Suffix Leukocytopenia

Word Roots: Leuk / (white)
cyt / (cell)
Combining Vowel / o /
Suffix: / penia (decrease) Med Term. Practice 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. Combining Forms Main part or foundation 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) Word Root FCTC Health Core Medical Terminology Pseudo- = False
Viscer/o = Organs of the Body
Ecto-, Exo- = Outside
Endo- = Inside
Meso- = Middle
Para- = Near, Beside, Around Ad-, ad = Toward
Gnos = knowledge
Dia = through
Aer/o = Air
Bi/o = Life, Living things
Chrom/o = Color
Stasis - = Act of Stopping, Controlling Common Terms 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. The rules appear on page 18 of the text. Plurality A prefix is a syllable or syllables placed BEFORE a word or word root to alter its meaning or create a new word.

Some prefixes:
Hyper- (excessive)
Pre- (before)
Post- (after)
Homo- (same)
Hypo- (under) Prefixes
-oma (tumor) hematoma
(blood tumor)

NOTE: The element that comes before a suffix can either be a word root or combining form. Suffix
-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) Meanings of certain 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. Suffixes By understanding the meanings of word roots, one can determine the meaning of complex medical terms by putting together the smaller parts. Word-Building System Anatomy
Ana/tomy comes from Greek word anatome meaning cutting apart.
Anatomy is the study of naming body structures. What is Anatomy? “dent” means tooth
“dermat” means skin
“cardi” means heart
“gastr” means stomach
“pancreat” means pancreas Word Root Examples The word root usually refers to a body part.
Some root words are derived from the Latin or Greek language. Word Origins Word Root
Combining Form

These four parts of a word are known as ELEMENTS. Basic Elements of a Medical Word Morbid
A higher offer
Cesarean Section
A district in Rome
Medical Staff
A doctor’s cane Euthanasia
Young people in Asia
A sheep dog
A punctuation mark
Minor Operation
Coal digging The Layman’s Medical Terms… Proximal


Cephal/o/caud/al Elbow is _______ to the hand
Ankle is _______ to the hip
Middle and side
Above and to the side
Head to tail More Practices… Near or on the back
Near or on the belly side
Toward the front, in front of
Following or located behind
Upward, toward the head
Downward, toward the tail
Toward the midline
Toward the side, away from the midline Dorsal dors/o
Ventral ventr/o
Anterior (ant) anter/o
Posterior (post)poster/o
Cephalic cephal/o
Caudal, caudad caud/o
Medial medi/o
Lateral later/o DIRECTIONS Combining vowel 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 Words Combining vowel Word root 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 Above
Near the point of origin
Away from the point of origin
Vertical, anteroposterior direction or plane dividing into left and right
Resembling a crown or encircling Superior super-
Inferior sub- or infra-
Proximal proxim/o
Distal dist/o
Sagittal sagitt/o

Coronal coron/o Directional Words Superior/Cephalic Distal-Away from a pint of origin Proximal-Closer to a point of origin Inferior/Caudal Slashes separate elements suffix Word root Combining vowel Word root 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 Combining Words LEFT RIGHT Lateral Medial Medial Lateral Posterior/Dorsal Anterior/Ventral MORE DIRECTIONAL TERMS Notice that there is no combining vowel in this word because the prefix ends with a vowel and the suffix begins with a vowel. BLOOD INSULIN LOW suffix Word root Prefix Hypoinsulinemia

Hypo / insulin / emia Prefix Transverse Plane=Any direction, like cutting the body in half. Coronal Plane =Lateral View Sagittal Plane=Anterior or Posterior View DIRECTIONS TAKE A WHILE TO GET DOWN, BE PATIENT Refer to the Glossary on Menu Bar for Common Medical Abbreviations Go to this Website if you want more Practice http://msjensen.cehd.umn.edu/1135/med_term_activites/default.html Now, Complete your worksheets and take your quiz!!

Medical Terminology will be a continual process in your program Please Review the DO NOT USE list.
