DefinitionIntroductory
What is the difference between the origin and insertion of a muscle as described in the chapter?
The origin of a muscle is the end attached to the bone that remains relatively stationary during movement, while the insertion is the end attached to the bone that moves during contraction.
Key points
- Muscle origin is attached to the less movable bone.
- Muscle insertion is attached to the more movable bone.
- The origin remains stationary, while the insertion moves during muscle contraction.
