What is an origin point?

Explanation:
An origin point is the fixed attachment of a muscle to the bone that remains stationary during contraction. This anchor end stays put while the muscle shortens, pulling on the other end (the insertion) to move the movable bone toward the origin. Because the origin is tied to the bone that doesn’t move much during the action—often near an immovable joint—it’s described as an attachment to an immovable joint. It isn’t about attaching to a tendon or a nerve, and the moving end of the muscle is the insertion, not the origin.
