forms deep cup in glenoid fossa
very fibrous ring
blends with biceps brachii tendon
glenoid labrum
superior middle inferior ligaments strengthen joint blend with labrum
glenohumeral ligaments
coracohumeral coracoacromial coracoclavicular acromioclavicular transverse humeral
stabilizing shoulder joint ligaments
protect muscle heads
sinovial membrane
thin loose covering
allows full movment
2 openings
shoulder articular joint capsule
1 for biceps brachii tendon
2 joint capsule and bursa
openings in shoulder joint capsule
