Medial bicipital groove

The medial bicipital groove is seen on the surface anatomy of the upper arm. It is formed by the hollow between the biceps and triceps muscles.

It should be distinguished from the bicipital groove or intertubercular sulcus, which is not a surface anatomy structure. It is the groove where the long head of biceps tendon runs between the greater and lesser tubercles below the humeral head before inserting into the superior glenoid rim.
