What causes a joint to move?
Joints don't have the ability to move. Joints are where two or more bones meet. One end of muscle attaches to the bone and the other end of the muscle stretches cross the joint and attaches to the bone on the other side of the joint. Muscles work in pairs, so that when one muscle contracts (the only movement that muscle can make), the other of the pair relaxes which causes movement at the joint when the bone is pulled by the muscle.
