Lining mucosa, which is nonkeratinized and has a softer surface texture, moist surface, and ability to stretch and be compressed, acting as a cushion for the underlying structures. Lining mucosa covers the inner surfaces of the cheeks and lips, the floor of the mouth, the ventral surface (under surface) of the tongue, the soft palate, and pharynx (throat). The masticatory mucosa, with its rubbery surface texture and resiliency, covers the hard palate and gingiva, and is attached firmly to the tissue underneath. Because these areas are directly exposed to masticatory forces, they are keratinized, having a callused surface.
