GLENOID CAVITY

The glenoid cavity forms the upper, lateral angle of the scapula, facing to the side of the body. This cavity serves as a site of articulation with the head of the humerus, or upper arm bone. Just to the posterior of the glenoid cavity is the acromion, which juts out from the spine of the scapula on its dorsal surface.
