Which of the following structure is intracapsular ?

Fibrous capsule envelopes the shoulder joint and is attached medially to the glenoid neck at a variable distance from the glenoid labrum,so forming recesses anterior and posterior to the scapular neck. The capsule includes the supraglenoid tubercle,to which the long head of biceps attaches,and which is therefore intracapsular.
