LO-HLTH8007

Welcome to Module 1

Module 1 (chapters 1-3) will enable you to learn about fundamental word structure including word roots, combining vowels, combining forms, prefixes and suffices. It will introduce areas pertaining to the human body terminology such as those used to describe locations on the body, major body cavities, cellular structure, genetics and body systems. With this acquired knowledge you will apply that knowledge to the human skeletal system.

In this module, you will be guided through individual lessons that correspond to chapters 1 through 3 in your textbook. Following this module, it is necessary to complete and submit assignment 1. Assignment one is located in the Assignments folder located on the left side of your desktop.

LESSON 1 – INTRODUCTION TO MEDICAL TERMINOLOGY

Text Reference: Chapter 1

Learning Objectives

Upon completion of this lesson, the student will be able to: -name the 4 types of word parts
-define commonly used word parts utilized in the formation of medical words -identify the meaning of unfamiliar words using word parts

Lets get started

Word Parts – The Building Blocks of Medical Terminology

-word parts are put together to form medical terms
-there are 4 types of word parts – word roots, combining forms, suffixes and prefixes -word roots give the essential meaning of the term
-word roots often refer to a body part
-combining forms consist of a root plus a combining vowel allowing a suffix to be added that does not begin with a vowel (note combining vowels can also connect one root to another). -a suffix is a word ending that often indicates either a condition, disease, procedures or disorder -a prefix is always at the beginning of a word and often indicates number, location, time or status

Examples of Word Part Usage

I will present you with 5 examples of Word Part Usage. At the end of each example I will ask you to determine the meaning of the word. Once you have considered this scroll down for the answer.

Hematology

Give it some thought and try to break down the word. Once you have completed your answer, see how it compares to mine.

Lets break the word down into parts

Hemat / o / logy

Hemat – word root meaning blood
o – combining vowel
logy – suffix meaning the study of

What do you think this one means? Give it some thought.

It means the study of blood

* Note how we came up with the meaning. You read it from the suffix (in this case “the study of”) and then read from the beginning across giving us the study of blood.

Electrocardiogram

Give it some thought and try to break down the word. Once you have completed your answer, see how it compares to mine below.

Lets break this word down into parts

Electr / o / cardi / o / gram

Electr – word root meaning electricity
o – combining vowel
cardi – word root meaning heart
gram – suffix meaning record

What do you think this one means? Think of the rule given with hematology and see what you come up with.

It means record of the electricity in the heart

*Note this one has a combining vowel between the two root words

Subgastric

Give it some thought and try to break down the word. Once you have completed your answer, see how it compares to mine below.

Sub / gastr / ic

Sub – prefix meaning below
Gastr – root meaning stomach
ic – suffix meaning pertaining to

Try to figure this one out on your own. What does it mean?

This one means pertaining to below the stomach

*Note there is no combining vowel between the prefix and root even though it starts with another consonant

Gastroenteritis

Give it some thought and try to break down the word. Once you have completed your answer, see how it compares to mine below....
