Abstract

The humerus, the largest and longest bone in the upper limb, has expanded ends and a shaft. The spheroidal humeral head forms an enarthrodial articulation with the glenoid fossa. The lesser tubercle is a projection from the front of the scapula shaft near the head. It is delimited on its lateral side. The intertubercular sulcus separates the well-marked groove from the greater tubercle. The distal end is adapted to the forearm bones at the elbow joint. It carries the medial and lateral epicondyles with the articular surfaces for the radius and ulna between them.
