Study Notes
Medical Terminology Origins
- Most medical terms stem from Greek or Latin, reflecting the historical foundations of modern medicine.
- The universal language during the development of Western medicine was Latin.
- Other languages influence medical terminology, with German, French, and modern English contributing new terms.
- Greek origins dominate diagnosis and surgery terms, while Latin is prevalent in anatomical terminology.
- Understanding the basic structure of medical terms, including prefixes, suffixes, and combining forms, helps decode their meaning.
Structure of Medical Terms
- Most medical terms consist of three core parts:
- Root: The fundamental meaning of the term
- Suffix: An ending that modifies the root
- Prefix: A word component at the beginning that alters the meaning of the root.
Combining Vowels and Rules
- A combining vowel, often "o," joins multiple roots or a root with a suffix starting with a consonant.
- If a suffix starts with a vowel, no combining vowel is needed.
- When a root ends in a vowel and the following suffix starts with the same vowel, omit the root's final vowel and use no combining vowel.
- Multiple roots will often have a combining vowel between them, even if a root begins with a vowel.
- If a prefix ends in a vowel, the final vowel of the prefix is frequently dropped when the following root starts with a vowel.
Root and Suffix Combinations
- Medical terms are built by combining at least one root with a suffix.
- The root provides the core subject, while the suffix modifies the root's meaning.
- For example, "lipemia" combines the root "lip" (fat) and suffix "emia" (blood condition), indicating fat in the blood.
- The term "lipidemia" combines the roots "lip," "oid," and "emia," further refining the meaning to specify a fat-related condition.
Prefixes and Their Impact
- Prefixes modify the meaning of the root(s) by being placed at the beginning of the term.
- For instance, in "hyperlipemia," the prefix "hyper" (excessive) alters the meaning of the root "lip" (fat) to imply an excess of fat in the blood.
Combined Roots
- Sometimes, medical terms include more than one root joined together.
- For example, "hyperlipoproteinemia" combines the elements:
- "hyper" (excessive)
- "lip" (fat)
- "o" (combining vowel)
- "protein" (protein)
- "emia" (blood condition)
- This structure indicates an elevated level of both fat and protein in the blood.
Combining Vowels and Combining Forms
- Combining vowels, primarily "o," are used between roots to enhance pronunciation.
- A combining form is essentially a root attached to a combining vowel.
Forming and Spelling Medical Terms
- Understanding prefixes, roots, and suffixes, along with rules for combining them, is essential for forming medical terms.
- A combining vowel ("o" most often) joins roots to roots or roots to suffixes starting with a consonant.
Medical Term Analysis
- Breaking down medical terms into components - suffix, prefix, and root(s) - provides a systematic approach to understanding their meaning.
- For instance, "pericarditis" reveals the following elements:
- "peri-" (around)
- "cardi-" (heart)
- "-itis" (inflammation)
- This analysis indicates inflammation around the heart.
Medical Term Formation with Examples
- Most medical terms are based on a root word, with prefixes and suffixes modifying its meaning.
- For example, using "cardi" (heart) as a basis:
- "cardi/ac" means pertaining to the heart.
Prefixes, Roots, Combining Vowels, and Suffixes: Heart and Lung Terminology
- The image provides various prefixes, roots, combining vowels, and suffixes related to the heart and lungs, aiding in constructing medical terms.
- Examples:
- epi/card/ium: tissue upon the heart (external lining).
- sub/endo/cardi/al: pertaining to beneath and within the heart.
- cardi/o/logy: study of the heart.
- cardi/o/pulmon/ary: pertaining to the heart and lungs.
- cardi/o/dynia: pain in the heart.
- cardi/o/rrhaphy: suture of the heart.

Plurals of Medical Terms
- Most medical terms follow standard English rules for pluralizing nouns.
- Consonants other than s, h, y: Add -s ("contusion" becomes "contusions").
- s, ch, sh: Add -es ("virus" becomes "viruses").
- y: Change y to i and add -es ("allergy" becomes "allergies").
General Notes on Term Formation
- Medical terms primarily combine roots, prefixes, and suffixes but have exceptions.
- Sometimes a single root can create a word.
- Occasionally, medical terms are formed by combining a prefix and a suffix.
Exceptions to Term Formation Rules
- Some medical terms may have unique structures or do not strictly adhere to the general rules of combining prefixes, roots, and suffixes.
- For example, "oviduct" combines "ovi" (egg) and "-duct" (to lead), while "metastasis" originated from "meta" (beyond, after, or change) and "-stasis" (stop or stand).
