Description

The oral cavity contains the teeth, gingivae (gums), tongue, palate, and palatine tonsils. It's divided into the vestibule and the oral cavity proper.

The vestibule of the oral cavity refers to the narrow space that lies between the lips and cheeks and the external surface of the teeth and gingivae (gums).

The oral cavity proper refers to the region that sits inside the dental arcades. Inferiorly, it’s bounded by the muscular floor of the mouth. Superiorly, it’s bounded by the palate and, posteriorly, by the oropharynx. The role of the oral cavity includes mastication and deglutition, in addition to ventilation and phonation.
