Usually, it has two heads long and short head originating from the supraglenoid
tubercle of scapula and from coracoid process of scapula.
The long head of the biceps tendon originates off of the supraglenoid
tubercle and is both intra-articular and extrasynovial.
The two heads of the biceps originate from the coracoid (short head) and the supraglenoid
tubercle of the humerous (long head), coalescing into a uniform muscle as they traverse the midpoint of the humerus (Figures 11,12A).
Type II SLAP lesion involves the detachment of the superior labrum and long head biceps tendon from the supraglenoid
It was traced at its beginning on the supraglenoid
tubercle of the scapula which passes over the extensor side of the shoulder joint through the intertuberal and runs distally along the craniomedial aspect of the humerus.
According to Gray (1977), Moore (2001), Di Dio (2002) the LHBBT originates in the supraglenoid

The acromioglenoid distance is the space between tip of acromion process and the supraglenoid
The short head arises by a thick flattened tendon from the apex of the coracoid process and the long head arises from the supraglenoid
tuberosity at the upper margin of the glenoid cavity, and is continuous with the glenoid labrum.
4) The long head of the biceps originates from the supraglenoid
tubercle of the scapula and superior glenoid rim.
Aortogram done--occlusion of cervical segment of left internal carotid artery just beyond the origin with faint reformation of supraglenoid
segment of internal carotid artery with narrowing of infrarenal aorta 4 cm below the origin of renal arteries with reformation of bilateral external iliac artery by collaterals.
At the twelve o'clock position, the superior labrum inserts directly into the long head of the biceps tendon, distal to the insertion of the biceps onto the supraglenoid
