The elbow is a simple hinge joint connecting the upper arm to the forearm. The joint is very stable because of its bones which include the upper arm (humerus) and the forearm bones (the radius and the ulna). Several muscles cross the elbow joint to allow it to flex and extend. Some of these muscles also allow the wrist to flex and extend. In addition, the elbow is stabilized by ligaments on the outside (lateral) and inside (medial) elbow.
