Medical Terminology and Word Analysis
Completion Requirements
- Understanding medical terminology requires the ability to break words into their components to decipher meaning.
- Each medical term often consists of a root, prefix, suffix, and combining vowel.
Components of Medical Terms
- Root: The essential meaning of the term.
- Prefix: A small part added to the beginning of the term.
- Suffix: A word ending that modifies the meaning of the root.
- Combining Vowel: Usually an "o" that connects roots to suffixes and roots to other roots.
- Combining Form: The combination of the root and the combining vowel.
Word Analysis
- Decoding Medical Terms:
- Break down terms into their components to understand their meaning.
- Example 1: ELECTR/ ext{O}/CARDI/ ext{O}/GRAM (means "record of electricity in the heart")
- Components:
- ELECTR: root (electricity)
- CARDI: root (heart)
- GRAM: suffix (record)
- Example 2: SUB/GASTR/IC (means "pertaining to under the stomach")
- Components:
- SUB: prefix (under)
- GASTR: root (stomach)
- IC: suffix (pertaining to)
General Rules for Decoding
1. Read medical terms from the suffix back to the beginning and then across.
2. Drop the combining vowel before a suffix that begins with a vowel (e.g., "gastritis" instead of "gastroitis").
3. Keep the combining vowel between roots, as in "gastroenterology."
Importance of Learning Word Parts
- Understanding medical terminology simplifies complex terms.
- Components of terms help avoid medical mistakes and improve comprehension.
- Example: Distinguishing between "hyperglycemia" (high blood sugar) and "hypoglycemia" (low blood sugar) by knowing prefix meanings (hyper: more; hypo: less).
Medical Roots, Prefixes and Suffixes
