The head of the radius has a cylindrical form, and on its upper surface is a shallow cup or fovea for articulation with the capitulum of the humerus.The circumference of the head is smooth; it is broad medially where it articulates with the radial notch of the ulna, narrow in the rest of its extent, which is embraced by the annular ligament. Its humeral head is small, and originates from the medial epicondyle; the origin of the ulnar head is extensive, and it attaches to the medial margin of the olecranon and proximal two-thirds of the posterior border of the ulna.
