Medical Terminology

Medical terminology is a great way to begin to learn the language of medicine.

Dedicate yourself to learn and strive for all you can…and you WILL succeed!

-Danyella O’Brien

medical terminology was derived primarily from greek latin
Medical Terminology was derived primarily from Greek & Latin

--these were the languages of scholarly people in ancient times

greeks the founders of modern medicine
Greeks: the founders of modern medicine
  • Hippocrates—
    • Four body humors:
    • black bile, yellow bile, blood & phlegm
    • Too much black bile caused depression
    • Called condition “melancholy”
    • Literally means:

“condition of black bile”

slide4
Because of this use of two different languages, you might see different terms & acronyms that mean the same thing.

Example:

  • EKG
  • ECG

- “K” (kardia) = heart --Greek

electro/kardio/gram

-“C” (cardia) = heart -- Latin

electro/cardio/gram

slide5
Impossible to memorize all the medical words individually, so determine meaning of words by breakingit into parts
  • These word parts are used over and over in different combinations
  • If the word parts are known, then the word can be broken down and interpreted
slide7

Greek mythology tells us of beautiful, fierce woman warriors.

Take the word Amazon.

  • They were excellent in archery & fighting.
  • They fought oppression of men.
  • Men called them Amazonwarriors.
what does the greek word amazon mean
What does the Greek word amazonmean?
  • Amazon comes from the Greek word: amazos
  • The “a” is a prefix that means “without”
  • “mazos” is the word root, which means “breast”
  • Translated, Amazon refers to “without a breast”
  • Greek mythology has it that these fierce women cut off their right breast in order to better handle their bows and arrows.
another interesting medical root is gastr o
Another interesting medical root is gastr/o
  • This root means stomach
  • gastr/itis = inflamed stomach
  • Gastr/ologist = stomach doctor
how is it then that the calf muscle is called the gastro cnemius muscle
How is it, then, that the calf muscle is called the gastrocnemius muscle?
  • In ancient times, gastr/o was a Greek word meaning “belly”
  • Since calf muscle “bellied” out, the root gastr/o was used to describe it.
medical words are like individual jigsaw puzzles
Medical words are like individual jigsaw puzzles--

each piece is a word part that comes together to form a medical term.

prefix

suffix

root

Example:

ologist

dermat

dermatologist = skin doctor

medical terms may have 4 word parts
Medical terms may have4word parts:
  • Root
  • Prefix
  • Suffix
  • Combining form
1 the word root
1. thewordroot
  • Gives basic meaning of term
  • each medical term contains one or more roots
  • Unlike English roots, which can stand alone, most medical roots are meant to be used in combinations.

Example: heart - cardi/

2 the prefix is
2.theprefixis
  • a word part added before a root to modify its meaning
  • many medical terms do not have a prefix

Example:pretest

a prefix usually indicates a
A prefix usually indicates a:
  • Number
  • Time
  • Position
  • Sense of negation
prefix examples
Prefix examples:
  • “number” prefixes
    • uni- (uni/corn)
    • bi- (bi/lateral)
    • tri- (tri/athlon)
  • “time” prefixes
    • pre- (pre/test)
    • post- (post/test)
slide20
“position” prefixes
    • sub- (sub/marine)
    • trans- (trans/atlantic)
    • hypo- (hypo/dermic)
  • “negation” prefixes
    • a- (a/moral)
    • an- (an/aerobic)
3 the suffix is
3. thesuffixis
  • a word part added to end of root to modify its meaning
  • most medical terms have a suffix

Example: root--teachto

teacher

in medical terminology a suffix often times indicates
In medical terminology, a suffix often times indicates:
  • a procedure ( -ectomy= surgical removal of)

append/ectomy

  • a condition ( -osis= abnormal condition of)

halit/osis

  • a disease ( -itis= inflammation of)

tonsill/itis

root prefix suffix examples
root/ prefix/suffixexamples:
  • Root example:write
  • Suffix example:writer
  • Prefix example:rewrite
  • See how both the suffix & prefix modify the root?
4 combining vowel
4. Combining Vowel
  • usually an “o” that is used between word parts
  • eases pronunciation

Examples: therm/o/meter

slide25

“i” or “e”

pelv/i or chol/e

  • occasionally other vowels are used:
  • A root word plus a vowel is referred to as a “combining form”.

combining form =

root =

hepat/

hepat/o

important
IMPORTANT:

Try to learn combining forms rather than word roots because:

combining forms are easier to pronounce.

Example:

Difficult to pronounce:

gastr

Easier to pronounce:

gastr/o

guidelines for using combining vowels
Guidelines For Using Combining Vowels
  • Rule 1
    • If asuffixbegins with a vowel, only use word root—not the combining form.
  • Example
    • suffix: -itis
    • root + suffix
    • hepat + -itis = hepat/itis
slide29

-If asuffixbegins with a consonant, use the combining vowel

  • Rule 2

Example:

wordroot

combin. vowel

suffix

therm/

o

-meter

rule 3
Rule 3
  • To link two root words, always use a combining vowel.

Example:

word roots

combin. vowel

suffix

splen/

o

hepat/

-itis

in most instances the combining vowel is retained between two roots
In most instances, the combining vowel is retained between two roots

-even if the 2nd root begins with a vowel.

word roots

combin. vowel

suffix

chondr/

o

arthr/

-algia

slide32

even if the last letter of the 1st root ends with a vowel (oste/)&

  • the 1st letter of the 2nd root begins with a vowel (arthr/),
  • you must still use the combining “o”
  • Example:
  • oste/+ o +arthr/+ -itis
slide33

Never use a combining vowel after a prefix, even if root begins with a consonant.

Rule 4

Example:

Never, never, NEVER!!!

NO “O” HERE!

three basic steps to defining interpreting medical words
Three Basic Steps to Defining & Interpreting Medical Words:
  • First, define the suffix
  • Second, define the prefix (if one is used)
  • Last, define the middle part (root) of word

Example 1: sub/gastr/algia

little note
little note…
  • the root for heart =cardi/
  • when you put this root with suffix,-itis, drop one “i”
  • instead of cardi/itis you would have:

carditis
