Lateral view of the human muscular system.
Skeletal muscles move bones by contracting and relaxing, which pulls on the bones via tendons. These muscles are attached to bones by tough connective tissues called tendons. When a muscle contracts, it shortens and pulls the tendon, which in turn moves the bone it's attached to. Many movements involve antagonistic muscle pairs, where one muscle contracts to produce a movement, and another muscle relaxes or contracts to oppose it. For example, bending and straightening the elbow involves opposing muscles. This coordinated action allows for precise and controlled movements of the body.12345
