NECK JOINT rOST-ERIORLY Joints of the Lower Jaw.—These are formed by the externallateral ligaments, short, thick bandsof fibres extending obliquely back-ward from the zygomas to the external surface of the necks of thefewer jaw; the capsular ligament, consisting of a few irregular fibrespassing from the edges of the glenoid cavities to the necks; the inter-articular fibrous cartilages, thin, oval plates, thicker at the edges thanin the centre, placed horizontally between the heads of the condylesand the glenoid cavities, thus dividing each joint into an upper and alower cavity; and the synovial membranes, one situated above and onabelow the cartilages. The movements of the lower jaw are depression and elevation,by which the mouth ij opened and shut; also a forward, backward,and lateral movement from si3e to side, constituting the grindingmntina.
