Elements of a Medical Terms • Roots • the constant, unchanging foundation of a medical term • usually of Greek or Latin origin • nearly all medical terms have one or more roots
Elements of a Medical Terms • Combining vowel • has no meaning of its own • joins a rootto another root • joins a root to a suffix • makes a word easier to pronounce • “o” is the most common combining vowel, followed by “a”
Elements of a Medical Term • Combining form • combines a rootand a combining vowel • can be attached to another root or combining form • can precede asuffix Example: enter/o
Elements of a Medical Term • Identify the elements of the following word: gynecologist gynec/ -o- -logist rootcombiningsuffix vowel
Greek, Latin, and Old English Words • Some medical terms do not break down (deconstruct) into word elements Examples: • Greek: toxin meaning poison • Latin: medical meaning toheal • Old English: record meaning to remember
Terms That Are Alike • Many words in the medical language are very similar. Examples: • ilium and ileum • malleus and malleolus
Chapter 1 Summary • Elements • prefix, root, combining vowel, combining form, and suffix • Greek, Latin, and Old English Words • Some do not break down • Terms That Are Alike • Look alike/sound alike
Suffixes • Added to the end of a root/combining form • Changes the meaning of medical terms • Use of combining vowel hemat -oma= root + suffix hemat/o -logist = root + combining vowel + suffix
Classification of Suffixes • Diagnostic • Diagnosis, procedure, or test • Surgical • Describes surgical procedures • Pathological • Describes a sign/symptom of a disease
Classification of Suffixes • Adjectives • 28 suffixes mean pertaining to • Nouns • do not fall under any classifications • maintain the root or combining form as a noun
Diagnostic Suffixes • Identify the suffixes of the following words: hematoma hemat/ -oma rootsuffix hematuria hemat/ -uria rootsuffix
Surgical Suffixes • Identify the suffixes of the following word: appendectomy append/ -ectomy rootsuffix lithotripsy lith/o -tripsy combining suffix form
Pathological Suffixes • Identify the suffixes of the following words: cystitis cyst/ -itis rootsuffix cyanosis cyan/ -osis rootsuffix
Adjective Suffixes Suffixes meaning pertaining to: -ac cardiac pertaining to the heart -arypulmonarypertaining to the lungs -iorposteriorpertaining to the back of the body
Noun Suffixes • Identify the suffixes of the following words: arteriole arteri/ -ole rootsuffix venule ven/ -ule rootsuffix
Prefixes • Added to the beginning of a medical term • Change the meaning of medical terms • No use of combining vowel peri-cardium = prefix + root epi-cardium = prefix + root
Position Prefixes • Identify the prefixes of the following words: epidermis epi- dermis prefix root hypodermis hypo dermis prefix root
Number and Measurement Prefixes • Identify the prefixes of the following word: multipara multi- para prefix root Primipara primi- para prefix root
Direction Prefixes • Identify the prefixes of the following word: antevert anti- vert prefix root synapse syn- apse prefix root
Element Review • Identify the prefixes and suffixes of the following word: hypogastric hypo- / gastr / -ic prefixrootsuffix
Chapter 2 Summary • Suffixes and Prefixes • Change the meaning of medical terms • Suffix • Added to the end of a root/combining form • Use of combining vowel • Prefix • Added to the beginning of a medical term
Decoding Terms • CARD Method • Check for the word parts in a term • Assign meanings to the word parts • Reverse the meaning of the suffix to the front of the definition • Define the term
Word Analysis, Definition & Pronounciation • Analyze the following term: endocarditis 1. suffix — itis meaning inflammation 2. prefix endo— meaning inside 3. root cardmeaning heart 4. put the terms together—inflammation of the inside of the heart
Building Terms • Spelling Rules • If the suffix starts with a vowel, a combining vowel is NOT needed to join the parts arthr/o itis = arthritis • If the suffix starts with a consonant, a combining vowel IS needed to join the two word parts arthr/o + plasty = arthroplasty
Building Terms • If a combining form ends with the same vowel that begins a suffix, one of the vowels is dropped Endo- + cardi/o + itis = Endocarditis • If two or more combining forms are used in a term, the combining form is retained Gastr/o + enter/0 + itis = Gastroenteritis
Building Terms • When two or more combining forms are used to make a medical term, special notice must be paid to the order in which the combining forms are joined Esophag/0 + gastr/o + duoden/o + scopy = Esophagogastroduodenoscopy (joining the CF reflects the direction in which the scope travels through the body)
Plurals • Singular / Plural Rules • Ends in –a add –ae vertebraae • Ends in -is add –esarthrosises • Ends in –ix or –ex add –ices appendixices • Ends in –itis add –itidesarthritisitides • Ends in –nx add –ngesphalanxnges • Ends in –um add an –a endocardiumia • Ends in –us add an –I digitusi • Ends in –y add –iesthearpyies
Chapter 3 Summary • Word Analysis and Definition • break it down into its component elements • Plurals and Pronunciations • memorize the plurals of medical terms • correct pronunciation is vital • Precision in Communication http://connect.mcgraw-hill.com/connectweb/login/?&node=connectdr_3
