Where the humerus sits in the skeleton
The humerus is the long bone of the upper arm, from shoulder to elbow. It forms the shoulder joint with the scapula above and the elbow joint with the radius and ulna below. Its upper end has a rounded head and the greater and lesser tubercles, with the tendon of the long head of the biceps running in the groove between them. At its lower end the capitulum meets the radius and the trochlea meets the ulna.
Frequently asked questions
Which part of the skeleton is the humerus in?
The humerus is one of the bones of the shoulder and arm. The clavicle and scapula attach the arm to the trunk, and the humerus, radius and ulna form the arm.
Which bones make up the shoulder and arm?
Each shoulder and arm is made of five bones: the clavicle, scapula, humerus, radius and ulna. The bones of the hand continue beyond them.
Is there one humerus or a pair?
The humerus is paired: there is one on the left and one on the right, and this page covers both.
Why does hitting the inner elbow tingle?
The ulnar nerve runs behind the medial epicondyle of the humerus just under the skin, so a knock there presses on the nerve.
