Coronoid process of the ulna - Wikipedia
The coronoid process of the ulna is a triangular process projecting forward from the anterior proximal portion of the ulna. Its base is continuous with the body of the bone, and of considerable strength. [1] Its apex is pointed, slightly curved upward, and in flexion of the forearm is received into the coronoid fossa of the humerus.
