. Anatomy, descriptive and applied. Anatomy. Fig. 230.—Temporomandibular articulation. Internal The stylomandibular ligament Qigamentum stylomandibulare) (Fig. 230) is a specialized band of the cervical fascia, which extends from near the apex of the styloid process of the temporal bone to the angle and posterior border of the ramus of the mandible, between the Masseter and Internal pterygoid muscles. This ligament separates the parotid from the submaxillary gland, and has attached to its inner side part of the fibres of origin of the Stylo- glossus muscle. Although usually classed among the ligaments of the mandible, it can be considered only as an accessory to the articu- lation. The capsular ligament {cap- sula articularis) (Figs. 229 and 230) forms a thin and loose cap- sule, passing from the circum- ference of the glenoid cavity and the articular surface immediately in front to the upper margin of the articular disk, and from the lower margin of the articular disk to the neck of the condyle of the mandible. It consists of very thin fibres, and is complete. It forms two joint cavities, distinct from each other, and separated by the articular disk. So thin is it that it is hardly to be considered as a distinct ligament; it is thickest at the back part, and thinnest on the inner side of the articulation.' The articular meniscus (discus articularis) (Fig. 231) is a thin plate of an oval form, placed horizontally between the condyle of the mandible and the glenoid cavity. Its upper surface is con- cavo-convex from before backward, and a little convex transversely, to accommodate itself to the form of the glenoid cavity. Its under sur- face, where it is in contact with the condyle, is concave. Its circumfer- ence is connected to the capsular ligament, and in front to the tendon of the External pterygoid muscle. It is thicker at its circumference, especially behind, than at its centre. The fibres of which it is composed have a concentric arrangement, more apparent a
