Humerus. The humerus is the long bone in the upper arm. It is located between the elbow joint and the shoulder. 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.
Humerus. Because it connects at the shoulder with a rotational joint, the humerus is instrumental in supporting many of the arm’s functions. For example, the humerus supports all lifting and physical activities. The humerus is one of the longest bones in the body. This means it is also one of the most commonly broken or fractured.
Anatomy Explorer. Red bone marrow, the tissue that produces new blood cells, is found in the ends of the humerus and supported by the trabeculae. 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,…This diagram with labels depicts and explains the details of Picture Of Humerus.
