【Biceps long head tendon function】

Biceps long head tendon through the humeral tuberosity It enters the anterior part of the subacromial space posteriorly and inserts into the supraglalenoid tuberosity of the scapula. The sliding of the tendon in the intertuberous groove of the humerus is passive, that is, the tendon slides upward when the shoulder joint is adduction, internal rotation, and extension, and slides downward when the shoulder is abducted, externally rotated, and flexed.

[Etiology]
