The glenoid surface for the articulation of the mandible is very wide.
The skull has been cut vertically in two at the plane of the glenoid fossae.
The articular surface, or head of the humerus, smooth and round, is in contact with the glenoid cavity of the scapula.
The region occupied by the glenoid cavity is separated from the body of the bone by a constriction—the neck of the scapula.
The anterior border (cervical) is strongly convex in the part next the glenoid cavity.
It arises above from a tubercle at the base of the coracoid process, which surmounts the glenoid cavity of the scapula.
The clavicle, coracoid, and scapula on each side form a bony articulation at the glenoid fossa.
The malar always extends back to form part of the glenoid cavity.
As in many Marsupials, the jugal bone sometimes extends backwards to the glenoid cavity, where the lower jaw articulates.
In addition to the part of the cranium anterior to the glenoid fossae, the lower jaws are preserved complete.
glenoid gle·noid (glē'noid', glěn'oid')
adj.
Relating to the articular depression of the scapula entering into the formation of the shoulder joint.
