Around the glenoid cavity is an area which is mainly ossified and is continuous with the scapula.

This has a more or less cylindrical shaft and articulates by a prominent rounded head with the glenoid cavity.

The coracoid is a large flattened blade-shaped bone forming about one-third of the glenoid cavity.

The scapula is a small somewhat rod-shaped bone forming about two-thirds of the glenoid cavity.

The glenoid articulating surfaces of both scapula and coracoid are lined by a thick pad of cartilage.
