The tendon of the long coracohumeeral of the Biceps brachii passes through the capsule and is enclosed in a tubular sheath of synovial membrane, which is reflected upon it from the summit of the glenoid cavity and is continued around the tendon into the intertubercular coracohumeraal as far as the surgical neck of the humerus.

Deep transverse metacarpal Superficial transverse metacarpal. The ligaments do not maintain the joint surfaces in apposition, because when they alone remain the humerus can be separated to a considerable extent from the glenoid cavity; their use, therefore, is to limit the amount of movement.
The arteries supplying the joint are articular branches of the anterior and posterior humeral circumflex, and transverse scapular. The second, which is not constant, is at the posterior part, where an opening sometimes exists between the joint and a bursal sac under the tendon of the Infraspinatus. Volume One Upper Limb 5th ed.

The bones entering into its formation are the hemispherical head of the humerus and the shallow glenoid cavity of the scapula, an arrangement which permits of very considerable movement, while the joint itself is protected against coracohumeeral by the tendons which surround it.
