bicipital groove
The bicipital groove (intertubercular groove, sulcus intertubercular) is a deep groove on the humerus that separates the greater tubercle from the lesser tubercle. The bicipital groove lodges the long tendon of the biceps brachii between the tendons of the pectoralis major on the lateral lip and the those of the teres major on the medial lip. It also transmits a branch of the anterior humeral circumflex artery to the shoulder-joint.
The insertion of the latissimus dorsi is found along the floor of the bicipital groove. The teres major inserts on the medial lip of the groove.
It runs obliquely downward, and ends near the junction of the upper with the middle third of the bone. It is the lateral wall of the axilla.
