Medical Terminology
| Term | Definition |
|---|---|
| Word Parts | Much of our medical terminology is built upon Greek and Latin word parts. These words can be broken down into smaller portions of the word. This allows you to figure out the word by knowing the meaning of each small portion. |
| Intravenous | Defined as “pertaining to within the vein.” |
| intra / ven / ous | “intra”: meaning “within” “ven”: meaning “vein” “ous”: meaning “pertaining to” |
| Eponyms | Medical terms that are named people who invented the technique or discovered the disease. Examples of medical eponyms include Parkinson’s disease and Alzheimer’s disease. |
| Acronyms | is a new word formed by the first letter or first few letters of multiple words. For example, did you know that LASER is actually an acronym? It’s a modern term that was formed from the phrase light amplification by stimulated emission of radiation |
| Many medical terms can be broken down into four parts. | Word Roots, Prefixes, Suffixes, Combining Vowels |
| Word Roots | Are the main part of the medical term. They’re what the rest of the term is built on. |
| Word Root for - intra / ven / ous | The main, or core, part of this word is “ven,” meaning “vein.” If you take out “ven” from the word, you have no meaning for the word |
| Prefixes | Prefixes come at the beginning of the word and modify the meaning. |
| Prefixes for-intra / ven / ous | "Intra" which means within, (When prefixes are offered alone, they’re written with the prefix and then a dash: “intra-.”) |
| Suffixes | Are similar to prefixes in that they modify the meaning of the word. However, suffixes come at the end of the word. |
| Suffixes for- intra / ven / ous | "Ous" Suffix for Intra-Ven-Ous -Ous meaning "pertaining to" It comes at the end of a word. It modifies the meaning of the term. |
| Combining Vowels | Combining vowels are vowels (a, e, i, o, u) that are placed between two word roots or a word root and a suffix to make the word easier to pronounce. |
| Example of Combining Vowels -Pathology | path / o / logy “path-” is the word root meaning “disease” ( o ) is the combining vowel -logy is the suffix meaning “study of” |
| Combining vowels can be used | Between two word roots Between a word root and the suffix |
| If you have a combining vowel that appears to be near the beginning of the word, it’s separating two word roots and not a prefix and a word root | Example- osteoarthritis - Oste-o-Arthr/itis (o) is the combining vowel but Oste is not the prefix because it's at the beginning of the word (not all words have prefixes) there are word roots -Oste & Arthr , a combining vowel (o) and a suffix -itis |
| Combining Forms | When you have a word root with a combining vowel attached, we call it the combining form. It’s just another way that helps us identify word parts in the process of defining them. |
| Example of combining forms using word Thermometer | There are three different word parts. therm / o / meter “therm”: word root “o”: combining vowel “meter”: (second) word root |
| Rules to Remember in Medical Terminology | Each medical term contains one or more word roots. Many medical terms don’t have a prefix. Most medical terms have a suffix. The combining vowel is usually “o,” not all medical terms have combining vowels. |
| Combining Vowels Rules to Remember | Combining vowels are never used between a prefix and a word root. A combining form is made up of a word root and a combining vowel, never a combining vowel and then a word root. |
