The humerus (Fig. 38) is typical of the long bones of the proximal and middle segments of the fore and hind limbs -n consisting of a central portion, the body or shaft of the bone, and of proximal and distal extremities for muscle j.^. attachment and articulation. The proxi- mal extremity bears on its medial side a smooth, convex projection, the head of the humerus (caput humeri), for articulation with the scapula. The articulation is nominally a ball-and-socket joint, or enar- throsis, but th° articulating surfaces are somewhat restricted, and the muscular arrangements of the limb are such that the ran£;e of lateral motion (abduction and adtluction) is small. Immediately in front of the head of the bone there is a small elevation, the lesser tubercle (tuberctilum minus). It is separated by a longitudinal furrow of the anterior suiface, the inter- tubercular groove (sulcus intertubercularis), from a much larger lateral elevation, the greater tubercle (tuberculum majus). Ex- tending distad from the latter is a tri- angular area the humeral spine (spina humeri), the i.^ of which reaches almost to the middle of the bone and forms a pronounced angle on its anterior surface. The distal extremity of the humerus bears a grooved articular surface, the trodUea humeri, for articulation with the radius and ulna. On its lateral side is a smaller surface, the capitulum humeri, for
