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.
Mouth (oral cavity) The mouth includes the lips, gums and tongue. The muscles of the base of the tongue (tongue base) continue into the upper throat (oropharynx). The roof of the mouth is called the hard palate. Behind this is the soft palate. The soft palate lifts to close off the passageways to the nose so food does not go through the nose when swallowing.
