elbow joint ELBOW JOINT

The elbow is a hinged joint made up of three bones: the humerus, ulna, and radius. The epiphysis is covered with cartilage tissue. Cartilage has a rubbery consistency that allows the joints to slide easily over each other and absorb shock.

Bones are held together by ligaments that form the joint capsule. A joint capsule is a fluid-filled sac that surrounds and lubricates a joint.

The important ligaments of the elbow are the medial collateral ligament (inner side of the elbow) and the lateral collateral ligament (outer side of the elbow). Together, these ligaments provide firm support to the humerus and ulna and are the primary source of elbow stability. Hold the ulna firmly together. The third ligament, the annular ligament, holds the radial head firmly against the ulna.
