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.
