Study Notes
Word-Building System
- Medical terminology is constructed through a system combining word roots, prefixes, and suffixes.
- Essential word roots include:
- Stomato (mouth)
- Dento (teeth)
- Gingiva (gums)
- Glosso/linguo (tongue)
- Nephro/reno (kidney)
- Encephalo (brain)
- Hepato (liver)
- Gastro (stomach)
- Entero (intestine)
Compound Words
- Compound medical words combine multiple word roots or a word root with a combining vowel.
- Examples of compound words include:
- Chicken + Pox = Chickenpox
- Underage, shorthand, download, brainstem
- Compound terms are formed using:
- Word root + combining vowel + word root
- Examples:
- Gastr/o + scope = Gastroscope
- Neur/o + surgery = Neurosurgery
- Micr/o + meter = Micrometer
- Hydr/o + phobia = Hydrophobia
- Hydr/o + therapy = Hydrotherapy
Prefixes and Suffixes
- Prefixes are added to the beginning of a word.
- Suffixes are appended to the end of a word.
- Examples of suffixes:
- Word root + Suffix = Noun (dent + ist = dentist)
- Word root + Suffix = Adjective (Anem + ic = Anemic)
Singular vs. Plural Forms
- Singular forms include:
- Sarcoma, Diagnosis, Phalanx, Coccus, Vertex, Cervix
- Plural forms change to:
- Sarcomata, Diagnoses, Phalanges, Cocci, Vertices, Cervices
Prefixes for Position
- Common prefixes indicating position include:
- Circum- (around)
- Peri- (around)
- Meta- (beyond, after)
- Retro- (behind)
- Ultra- (beyond, in excess)
- Meso- (middle)
Body Planes
- Body planes help describe anatomical positions:
- Coronal Plane: Cuts body into anterior and posterior halves.
- Sagittal Plane: Vertical division into equal right and left halves.
Directional Terms
- Medial: Toward the middle (medi/o)
- Lateral: Towards the side (later/o)
- Anterior: Front (anter/o)
- Posterior: Back (poster/o)
Combined Directional Terms
- Anterolateral: Front and side.
- Anteromedial: Front and middle.
- Anterosuperior: Front and top.
- Posterolateral: Back and side.
- Posterexternal: Back and outside.
- Posterinternal: Back and inside.
