Do muscle push bones to make them move?

Muscles do not directly push on bones to move them. Instead, muscles work by contracting and relaxing, which pulls on the bones and causes them to move. When a muscle contracts, it shortens and pulls the bone that it is attached to closer to its origin, which is the point where the muscle attaches to the bone. When a muscle relaxes, it lengthens and allows the bone to move back to its original position.
