Intertubercular groove
Encyclopedia
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.
It is the lateral wall of the axilla.
