The bone of the upper forelimb, extending from shoulder to elbow. It consists of a shaft and two enlarged extremities. The proximal end has a smooth round head that articulates with the scapula to form the shoulder joint. Just below the head are two rounded processes called the greater and lesser tubercles. The distal end of the humerus has a trochlea, which articulates with the ulna, and a capitulum, which articulates with the radius, at the elbow.

The axillary nerve

The most common type of shoulder dislocation is an anterior or inferior dislocation of the humerus of the glenohumeral joint. This dislocation has the potential to injure the axillary nerve or axillary artery. Signs and symptoms of this dislocation include a loss of the normal shoulder contour and a palpable depression under the acromion.

The Ulnar Nerve

The ulnar nerve at the distal end of the humerus near the elbow is sometimes referred to in popular culture as 'the funny bone'. Striking this nerve can cause a tingling sensation ("funny" feeling), and sometimes a significant amount of pain.
