The medial epicondyle of the humerus, larger and more prominent than the lateral epicondyle, is directed a little backward. In birds, where the arm is somewhat rotated compared to other tetrapods, it is called ventral epicondyle of the humerus.

It gives attachment to the ulnar collateral ligament of the elbow-joint, to the Pronator teres, and to a common tendon of origin (the common flexor tendon) of some of the Flexor muscles of the forearm.

The ulnar nerve runs in a groove on the back of this epicondyle.
