  1. Medical Terminology

  2. Objectives • Upon completion of this unit you will be able to: • Identify and define the four word parts • Identify and define a combining form • Analyze and define medical terms • Build medical terms for given definitions

  3. Mrs. Jones is a 60 y/o admitted thru ER c abdominal pain in the RLQ. CXR, EKG, CBC and ABG’s were done stat. It was decided to perform an exploratory laparotomy, but suspects she will end up needing a bilateral salpingoophorectomy.

  5. Origins of medical language • Current medical vocabulary includes terms built from Greek and Latin word parts, some which were used by Hippocrates and Aristotle over 2000 years ago

  6. Word Parts / Building Blocks • Medical terms are built from word parts with some or all of the following components: • Word roots • Suffixes • Prefixes • Combining vowels • Combining forms

  7. The word root is the foundation of the word Usually indicates the part of the body involved All medical terms must have one or more word roots Word Root

  8. Examples: • In the word…………………..play/er (play is the word root) • In the medical term …………arthr/itis arthr(which means joint) is the word root • In the medical term………….hepat/it is hepat(which means liver) is the word root

  9. Suffixes • Suffix is the word part attached to the end of the word root to modify its meaning. • The suffix usually indicates the procedure, disease, or condition • All medical terms musthave a suffix.

  10. Examples: • In the medical term…………..hepat/ic -ic(which means pertaining to) is the suffix The term hepatic means pertaining to the liver • In the medical term ………… hepat/itis -itis(which means inflammation) is the suffix The term hepatitis means inflammation of the liver (inflammation being a condition)

  11. Prefix • The prefix is a word part that is attached to the beginning of the word root to modify its meaning. • It usually indicates location, time, color, or number • Not all medical terms have prefixes

  12. Examples: • In the word ………………...re/play re- is the prefix • In the medical term ………sub /hepat /ic sub- (which means under) The medical term subhepatic means pertaining to under the liver

  13. Combining Vowel • It links the root to the suffix or the root to another root • The combining vowel is usually an “O” • A combining vowel has no meaning of its own. It just joins word parts and makes them easier to pronounce

  14. Combining vowels • Guideline #1: • When connecting a root and a suffix a combining vowel is used unless the suffix begins with a vowel • Guideline #2: • When connecting two word roots, a combining vowel is usually used even if vowels are present at the junction

  15. Exercise 1: Complete the phrases with the correct word part: • A __ is attached at the beginning of a word root • ___ are usually an “o” • All medical terms contain one or more ___ 4. A ____is attached at the end of a word root. 5. The ______ _____ is the word root with the combining vowel attached • True or False • There is always a prefix at the beginning of a medical term • A combining vowel is always used when connecting a word root and a suffix • A prefix modifies the meaning of the word • A combining vowel is used to ease pronunciation • “I” is the most commonly used combing vowel • The word root is the core of a medical term • A combining vowel is used between a prefix and word root • A combining form is a word part

  16. Analyzing and defining Medical Terms osteoarthropathy To analyze a medical term divide it into word parts, label each word parts, and label the combining forms. Divide the word with slashes: oste / o/ arthr / o/ pathy Label each word part by using the following abbreviations: WR WORD ROOT P PREFIX S SUFFIX CV COMBINING VOWEL

  17. Example of dividing and labeling: WR CV WR CV S Oste / o / arthr /o / pathy CFCF

  18. Putting it together! • To define medical terms apply the meaning of each word part in the term. • Begin by defining the suffix, then move to the beginning of the term to complete the definition
