What causes a joint to move?

Joints don't have the ability to move. Joints are where two or more bones meet.

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.
