Humerus - Definition

Ask a question


The humerus bone is located in the arm. It is connected at the shoulder with the scapula and at the elbow with the bones of the forearm, the radius and the ulna. The humerus is a long bone, whose long central portion is triangular and has three faces. It coexists with the axillary, radial, and ulnar nerve, which innervate the fingers, hand, forearm, and arm, and blood vessels to and from these areas. In the case of trauma, fracture of the humerus is possible and may affect the upper end of the humerus, the body of the humerus, or the lower end.
