    a voluntary muscle usually works across a joint.origin and insertion:when a muscle contracts, usually just one bone moves. the other is stationary. the origin is where the muscle joins the stationary bone. the insertion is where it joins the moving bone. when a muscle contracts, the insertion moves towards the origin.
