The action of a muscle is determined by its anatomical structure, including its origin, insertion, and the orientation of its fibers. Additionally, the type of muscle fibers (such as slow-twitch or fast-twitch) and the neural signals it receives play crucial roles in its function. The leverage provided by the skeletal system and the joints also influences the range and type of movement generated by the muscle.
