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, like many organs in the human body, is a hollow cavity. The part in front of the teeth is called the vestibule, while the part behind is the mouth itself. The floor of the mouth is formed from sheets of muscle tissue which are attached to the inner surface of the jawbone, or mandible.
