Abstract

The chapter discusses about the entrance of the digestive system which is mouth or oral cavity. There are two parts of oral cavity, the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. The oral vestibule is bounded externally by the lips, cheeks and mucosa, and internally by the alveolar processes and the teeth and gums. The oral cavity proper is the inner larger part. Both these parts interact only through a gap between the last molars and the ramus of the mandible, when the teeth are in contact. Oral cavity proper is surrounded by alveolar arches, teeth and gums, and palate and tongue. A median fold of mucous membrane termed as frenulum attaches the inferior surface of the tongue to the floor of the mouth. Salivary glands are meant for the production of saliva.
