At the elbow, it connects primarily to the ulna, as the forearm’s radial bone connects to the wrist. At the shoulder, the humerus connects to the frame of the body via the glenoid fossa of the scapula.

The hollow medullary cavity in the middle of the shaft of the humerus is filled with fatty yellow bone marrow for energy storage. Compact bone forms the largest and strongest structure in the humerus,…
