The greater and lesser tubercles of the humerus are separated from each other by a deep groove, the intertubercular groove (bicipital groove, sulcus intertubercular), which lodges the long tendon of the Biceps Brachii muscle between the tendons of Pectoralis Major on the lateral lip and Teres Major on the medial lip. It also transmits a branch of the anterior humeral circumflex artery to the shoulder-joint.
The insertion of Latissimus Dorsi is found along the floor of the intertubercular sulcus.
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.[1]
