How do muscles move the bones?
Muscles provide the tug on the bones needed to bend, straighten, and support joints . Muscles can pull on bones, but they can’t push them back to their original position, so the muscles work in pairs of flexors and extensors. The extensor muscle relaxes and stretches as the flexor muscle contracts to bend the joint.
