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 back of the mouth where it meets the throat is called the oropharynx (or o far inx). This region includes all of the soft palate, the tonsil region, and the back of the tongue where it goes out of view, extending down towards the voice box (larynx).
