Glenoid Fossa

A bony cup, or depression, which faces downward (open end of cup faces down) located on either side of the skull in the temporal bone. The lower jaw ends (condyles) fit into these fossae. A complex web of ligaments and muscles holds the lower jaw in place. A cartilaginous disk is interposed between the condyle and the fossae (see "DISK"). The front slope of the fossa is called
the eminance. During wide opening, the condyles slide down the eminances (hopefully with the disks in-between!)
