Origin (anatomy)
Introduction
The origin of a muscle is the point at it attaches to a bone (usually) or another muscle. The structure that the origin is attached to is not moved by the contraction of the muscle[1]. The opposite end of the muscle is called the insertion.
The origin is one end of the muscle that is attached to a bone that does not move when the muscle contracts.
