glenoid cavity n.
The hollow in the head of the scapula into which the head of the humerus sits to make the shoulder joint. Also called glenoid fossa.
As in many Marsupials, the jugal bone sometimes extends backwards to the glenoid cavity, where the lower jaw articulates.
The anterior border (cervical) is strongly convex in the part next the glenoid cavity.
This has a more or less cylindrical shaft and articulates by a prominent rounded head with the glenoid cavity.
The malar always extends back to form part of the glenoid cavity.
When the mouth is opened wide, the condyle advances out of the glenoid cavity, and returns to its socket when the mouth is shut.
The joint is freely exposed, the capsule divided, the head of the bone freed and returned to the glenoid cavity.
It arises above from a tubercle at the base of the coracoid process, which surmounts the glenoid cavity of the scapula.
A partial fracture carrying away the lower part of the glenoid cavity simulates a sub-glenoid dislocation.
The region occupied by the glenoid cavity is separated from the body of the bone by a constriction—the neck of the scapula.
The glenoid cavity is deformed or absent, and the dislocation may be sub-coracoid, sub-acromial, or sub-spinous.
