The humerus articulates with the scapula at the: O superior border O glenoid fossa O scapular spine O acromion process O coracoid process

Due to the general glenohumeral joint's articulation, the shoulder is anatomically and functionally complicated. It is one of the most freely movable regions of the human body. It houses the shoulder girdle, which, through the sternoclavicular joint, links the upper limb to the axial skeleton. The shoulder's great range of motion comes at the price of the joint's stability, making it prone to dislocation and damage.
