ball and socket joints are the most freely moving of all the joints in the human body.

Muscles,bones and joints all work together to bring around movement . Muscles are attached to the bone. When a muscle gets shoter it then pulls the bone that is attached to, which then makes it it move at the joint.
A bone is like a lever which the muscle applies force.
