Programmed Learning Technique
•Consists of a series of teaching units called frames. •Each frame presents information and calls for an answer on your part. •Study frames in sequence because each frame builds on the previous one. •Do not look at the answer column before you write your response, and do not move ahead in a chapter.
Medical words consist of some or all of the following elements (word parts):
•Word root (W R) •Combining form (C F) •Suffix •Prefix
Word Root (W R)
•Foundation of a medical word that contains its main meaning. •Usually derived from Latin or Greek language. Most medical words contain at least one W R
Combining Form (C F)
•Created when a W R is combined with a vowel, known as a combining vowel. No meaning of its own, but enables two or more word elements to be connected.
•Combining vowel usually an
o, but sometimes an i or an e.
•Difficulty pronouncing certain combinations of W R’s requires
insertion of a vowel.
•mamm/o in mamm/o/gram
CF
•psych/o in psych/o/logy
CF
•laryng/o in laryng/o/spasm
CF
hepat/o in hepat/o/megaly
CF
Suffix
•Word element at the end of a word. •Changes the meaning of a medical word. •Contained in most medical words. •Usually an indication of a pathology, condition, symptom, therapeutic or diagnostic procedure, or part of speech.
•-ectomy in append/ectomy
Suffix
•-itis in appendic/itis
Suffix
•-oma in neur/oma
Suffix
•-tomy in crani/o/tomy
Suffix
•-scope in gastr/o/scope
Suffix
-oma in gastr/oma
Suffix
Prefix
•Word element at the beginning of a word. •Many are the same as those used in the English language. •Changes the meaning of a medical word. •Not contained in all medical words. •Usually an indication of a number, time, position, measurement, direction, or negation.
•hyper- in hyper/tension
Prefix
•hemi- in hemi/plegia
Prefix
•epi- in epi/derm/al
Prefix
•post- in post/nat/al
Prefix
inter- in inter/cost/al
Prefix
Three steps for defining medical words:
1.Define the suffix first. 2.Define the first part of the word (W R, C F, or prefix). 3.Define the middle part of the word (W R or C F).
Three rules for building medical words:
Know your rules 1, 2, 3
•Rule 1:
W R links a suffix that begins with a vowel.
•Rule 2:
C F (root + o) links a suffix that begins with a consonant.
•Rule 3:
C F (root + o) links a root to another root to form a compound word. •Rule 3 holds true even if the next root begins with a vowel, as in gastr/o/intestin/al.
•Diacritical marks and capitalization are used to
aid pronunciation of terms throughout the text and to help you understand pronunciation marks used in most dictionaries.
