Medical Terminology Health Science Technology Objectives Identify basic medical abbreviations selected from a standard list Define prefixes, suffixes and word roots selected from a list of words Spell and pronounce medical terms correctly Word Parts Word roots Suffixes Prefixes Combining vowels Word Root A word root is the word part that is the core of the word
Contains the fundamental meaning of the word and explains what part of the body is being talked about Examples Neur/o= nerves Hepat/o= liver Arthr/o= joint Word Root Because the word root contains the fundamental meaning of the word, each medical term contains one or more word roots. Suffix A word part attached to the end of the word root to modify its meaning; indicates the procedure, disease, or condition Examples -itis=inflammation algia= pain ic= pertaining to ous= pertaining to Prefix A word part attached to the beginning of a word root to modify its meaning; usually indicates location, time, or number.Not all words have prefixes. Examples Sub= under or below Poly= many Post= after Intra= within Peri= surround or protect Pre= before Combining Vowel Combining vowel is a word part, usually an O, and is used: Between two word roots It is NOT used when a suffix begins with a vowel -IS used when a suffix begins with a consonant Combining Form A word root with the combing vowel attached, separated by a vertical slash Arthr/o= joint Oste/o= bone ven/o= vein Defining Medical Terms
Begin by defining the suffix, then move to the beginning of the term to complete the definition (does not apply to all medical terms) Putting Medical Terms Together
