Study Notes
Word Root
- Word root is the core part of a medical term.
- It's often of Greek or Latin origin.
- Examples of word roots include:
- lithos (G., stone)
- psyche (G., mind)
- cauda (L., tail)
- oris (L., mouth)
Combining Vowel
- A combining vowel (often "o") is inserted between word roots to improve pronunciation.
- This improves pronunciation clarity and improves the flow of the words.
- Examples include:
- Cardio (heart)
- Gastro (stomach)
- Osteo (bone)
Prefixes and Suffixes
- Word roots are often accompanied by prefixes and/or suffixes.
- Prefixes are placed before the word root.
- Suffixes are placed after the word root.
- A hyphen often follows a prefix if it's used alone, indicating more words will follow.
- Example: a-febrile (without fever)
- Example: anti-viral (against viruses)
Suffixes
- Suffixes modify the meaning of the word.
- They are attached to the end of the word root.
- Suffixes are usually preceded by a hyphen.
- Example: Erythr/o (red)+cyte (cell) = red blood cell
- Example: dys- (bad) + -pnea (breathing) = dyspnea( difficulty breathing)
Combining Vowels and Suffixes
- If a suffix begins with a vowel, the combining vowel is omitted.
- Example: hepat/o + itis = hepatitis
- Most prefixes end in a vowel and can be added to other words with no changes
- Example: pre + cancer = precancerous
- Example: anti + biotic = antibiotic
Eponyms
- Eponyms are terms for diseases, organs, procedures, or body functions named after a person.
- Example: Parkinson disease, Alzheimer's disease, Caesarean section
Abbreviations and Medical Terms
- Abbreviations are shortened words or phrases used in medical contexts
- Example: MD (Doctor of medicine)
- Example: SOB (shortness of breath)
- Example: Stat (immediately)
- Acronyms are pronounceable, word-like names made of the first letters of multiple words.
- Example: CABG (Coronary artery bypass graft)
Plurals
- For most medical terms, add "s" to the singular form to create the plural.
- For some terms, add "-es" to create plurals
- Example: Abrasion(singular) - Abrasions (plural)
- Example: Sinus (singular) - Sinuses (plural)
- Some terms need a vowel change from "y" to "i" when adding "-es" for the plural.
- Example: Allergy - Allergies
