What it is and what it does

The elbow is the joint between the upper arm and the forearm, formed by the humerus, radius and ulna. The point of the elbow, the bump you can easily feel with your fingers, is the olecranon, the upper end of the ulna. The elbow bends in a single plane, forward and backward, like a hinge.

Worth remembering

The point of the elbow is an extension of one of the two bones of the forearm.
