Quizplus · Accepted Answer

The indentation on the posterior surface of the distal epiphysis of the humerus is the olecranon fossa, which accommodates the olecranon process of the ulna when the elbow is extended. The trochlear notch is a feature of the proximal ulna, the coronoid fossa is a feature of the anterior surface of the distal humerus, and the radial groove runs along the posterior aspect of the humeral shaft.
