This is a ginglymo-arthrodial joint; the parts entering into its formation on each side are, above, the anterior part of the glenoid cavity of the temporal bone and the eminentia articularis; and, below, the condyle of the mandible. The ligaments are the following: External Lateral. Internal Lateral. Articular Disk Stylomandibular. Capsular. The external lateral ligament {ligamenium temporomaitdibulare) (Fig. 229) is a short, thin, and narrow fasciculus

The ligaments are the following: External Lateral. Internal Lateral. Articular Disk Stylomandibular. Capsular. The external lateral ligament {ligamenium temporomaitdibulare) (Fig. 229) is a short, thin, and narrow fasciculus, attached, above, to the outer surface of the zygoma and to the tubercle on its lower border; beloiv, to the outer border of the neck and to the tubercle at the outer extremity of the condyle of the mandible. It is broader above than below; its fibres are placed parallel to one another, ss»m\ ^ ^^^^ Temporal bone. k\ , ,A. Fig. 229.—Tempoi and directed obliquely downward and backward. Externally, it is covered by the parotid gland and by the integument. Internally it is in relation with the capsular ligament, of which it is an accessory band, and from which it is not separable. The internal lateral ligament (licfamentum sphenomandibulare) (Fig. 230) is .a flat, thin band which is attached above to the spine of the sphenoid bone, and, becoming broader as it descends, is inserted into the margin of the dental foramen and the portion of bone, the lingula, which overhangs the foramen in front. This ligament is not a true articular ligament, but is an accessory band, contrib- uted to the capsule by the deep cervical fascia. Its outer surface is in relation, above, with the External pterygoid muscle; lower down it is separated from the neck of the condyle by the internal maxillary artery; and still more inferiorly, the inferior dental vessels and nerve separate it from the ramus of the mandible. The inner surface is in relation with the Internal Please note that these
