110, The Right Shoulder-Joint, Articulatio humerL 



The shoulder -joint is surrounded by a lax fibrous capsule, 

 which is strengthened by the coraco-humeral or accessory and glenoid 

 ligaments. The articulation is free on all sides, only at the superior 

 circumference it is protected by the coraco-acromial ligament which is 

 spread like a bridge between the acromion and coracoid processes. The 

 fibrous capsule, which stretches from the circumference of the glenoid 

 cavity of the scapula to the anatomical neck of the humerus, covers 

 the bicipital groove between both tuberosities, thereby changing it into 

 a canal.
