head of radius

^ http://purl.obolibrary.org/obo/UBERON_0001012

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 (or capitellum) 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. The deepest point in the fovea is not axi-symmetric with the long axis of the radius, creating a cam effect during pronation and supination[WP]. [ http://en.wikipedia.org/wiki/Head_of_radius ]
