![]() ![]() Quantitatively, the larger part of the oral mucosa is represented by lining mucosa, amounting to about 60% of the total area, with masticatory mucosa and specialized mucosa occupying smaller areas (25% and 15%, respectively).Īlthough the oral mucosa is continuous with the skin, it differs considerably in appearance. Figure 12-1 shows the anatomic location of each type diagrammatically, and the types are described fully later in the chapter. The oral mucosa shows considerable structural variation in different regions of the oral cavity, but three main types of mucosa can be recognized, identified according to their primary function: masticatory mucosa, lining mucosa, and specialized mucosa. Posteriorly the oral cavity is bounded by the pillars of the fauces and the tonsils. The hard and soft palates form the superior zone of the oral cavity proper, and the floor of the mouth and base of the tongue form the inferior border. The oral cavity consists of two parts: an outer vestibule, bounded by the lips and cheeks, and the oral cavity proper, separated from the vestibule by alveolar bone and gingiva. ![]()
