The shoulder joint is made up of the glenoid and humeral head. The humeral head is ball-shaped but the glenoid is more dish-shaped than cup-shaped. To aid stability of the joint, the glenoid has a soft tissue bumper around its edge (the labrum) which acts as a bumper preventing dislocation of the head from the glenoid.
