=Ox.=—The articular surfaces are of such a character as to permit more
extensive lateral movement than in the horse.
The condyle of the mandible is relatively small and is concave
transversely. The temporal articular surface is extensive and is
convex in both directions. The postglenoid process is small.
=Pig.=—The considerable longitudinal diameter of the temporal articular
surfaces and the very small size of the postglenoid process allow great
freedom of protraction and retraction of the lower jaw. Lateral movement
is limited. The posterior ligament is absent.
=Dog.=—The articular surfaces allow extremely little lateral or gliding
movement. They are cylindrical in curvature, and the interarticular disc
is very thin. The posterior ligament is absent.
The other articulations of the skull are sufficiently described in the
Osteology.
