Notes on Usage
- "Cơ khít" is a technical compound noun formed from "cơ" (muscle) and "khít" (tight, close-fitting). Its meaning is directly derived from this combination: a muscle that makes something tight or closed.
- In most practical contexts, especially in modern medical Vietnamese, the more specific term "cơ thắt" (sphincter) is preferred for describing muscles that close tubular structures. "Cơ khít" may be encountered in older texts or as a general descriptive term.
