Preferred Label : head of radius;
Uberon definition : 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].;
