Intertubercular groove Location
The Intertubercular groove of the humerus runs between the lesser and greater tubercles that are located at the humerus’ proximal end. The tendon of the biceps brachii muscle’s long head, along with a tendon sheath, passes through this groove.

It serves as the axilla’s lateral wall. It also directs an anterior humeral circumflex artery branch to the joint of the shoulder.
