Capitulum of the humerus

Capitulum of the humerus
Bone: Capitulum of the humerus
Left humerus. Anterior view. (Capitulum visible at bottom right.)
Latin capitulum humeri
Gray's subject #51 212

In human anatomy of the arm, the lateral portion of the articular surface of the humerus consists of a smooth, rounded eminence, named the capitulum of the humerus.

It articulates with the cupshaped depression on the head of the radius, and is limited to the front and lower part of the bone.

In birds, where forelimb anatomy has adaptation for flight, its functional if not[verification needed] ontogenetic equivalent is the dorsal condyle of the humerus.
