The lesser tubercle provides insertion to subscapularis muscle. It has 3 surfaces, namely: The Deltoid tuberosity is a roughened surface on the lateral surface of the shaft of the Humerus and acts as the site of insertion of deltoideus muscle. Its upper surface is rounded and marked by three flat impressions: the highest of these gives insertion to the supraspinatus muscle; the middle to the infraspinatus muscle; the lowest one, and the body of the bone for about 2.5 cm. The proximal end is rounded, while the distal end is ventrodorsally flattened. The axillary nerve is located at the proximal end, against the shoulder girdle. In long bones, as you move from the outer cortical compact bone to the inner medullary cavity, the bone transitions to spongy bone. Above the back part of the trochlea is a deep triangular depression, the olecranon fossa, in which the summit of the olecranon is received in extension of the forearm.
