New aspects on the topography of the tendon of the long head of the biceps brachii muscle. One more stabilizer factor of the shoulder joint.
There are little variations in descriptions on the origin of the tendon of the long head of the biceps brachii muscle, in the classical text books of Anatomy. Most authors define as the main origin of the tendon of the long head of the biceps brachii muscle, the supraglenoid tubercle and adjoining part of the glenoid labrum of the scapula. In the present study we found that the origin of the tendon of the long head of the biceps brachii muscle extended towards almost the whole periphery of the glenoid cavity on the glenoid labrum except from a small area near to the supraglenoid tubercle.
