Anatomy of the mouth. The mouth, consists of 2 regions, the vestibule and the oral cavity proper. The vestibule is the area between the teeth, lips and cheeks. The oral cavity is bounded at the sides and in front by the alveolar process (containing the teeth) and at the back by the isthmus of the fauces.
The mouth, also called the oral cavity, is the first part of the gastrointestinal tract (or alimentary canal). The boundaries of the mouth are formed by the lips, cheeks, floor of the mouth, and palate. The mouth contains the teeth and tongue and receives secretions from the salivary glands. It performs three main functions, which have to do with digestion, breathing, and speech.
