Intertubercular groove

The 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 and transmits a branch of the anterior humeral circumflex artery to the shoulder-joint.

It runs obliquely downward, and ends near the junction of the upper with the middle third of the bone.
