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 palate is the term used for the roof of the mouth, which separates it from the nasal cavity. It is divided into two parts: the hard palate and the soft palate. The hard palate is the part of the palate close to the front of the mouth. It is an immovable bony structure covered by mucous membrane that forms an arch over the teeth of the upper jaw.
