Feb 23, 2024 · Muscle insertion is the point where the muscle attaches to the bone or structure that it moves. This is usually the more mobile end of the muscle, located distally, or further from the center of the body. When the muscle contracts, it pulls on this insertion point, causing movement.

Sep 26, 2024 · The end of the muscle attached to a fixed (stabilized) bone is called the origin and the moveable end of the muscle that attaches to the bone being pulled is called the muscle’s insertion. The muscle's line of pull indicates the direction the body part will move when the insertion point is brought closer to the origin point (Figure \(\PageIndex{1}\)).
The origin and insertion of a muscle determine its movement by dictating which part of the body will move when the muscle contracts. The insertion, being the mobile attachment, moves towards the origin, the stationary attachment. For instance, during knee flexion, the bicep femoris muscle pulls the tibia (insertion) closer to the ischium ...
The end of the muscle attached to a fixed (stabilized) bone is called the origin and the moveable end of the muscle that attaches to the bone being pulled is called the muscle’s insertion. Although a number of muscles may be involved in an action, the principal muscle involved is called the prime mover, or agonist.
