(Latin: shoulder, upper arm; pertaining to the bone that extends from the shoulder to the elbow)
Usually movements of the fracture of the humerus at the elbow and wrist are started early, and active conditions of the shoulder will begin in about three weeks.
The largest ulna part articulates with the humerus at the elbow joint and the smallest portion of the ulna articulates with the carpal bones in the wrist.
2. The long bone of the human upper arm or of a forelimb in other animals.
3. The bones of the upper arms, extending from the elbows to the shoulders; the humeri.
4. The long bone of the upper forelimb in tetrapods; the upper arm bone in humans, extending from the shoulder to the elbow.
Its rounded upper head articulates with the glenoid cavity of the scapula in a ball-and-socket joint.
The lower end is modified to form an articular surface (condyle) for the radius and the ulna, which produce the hinge joint of the elbow.
