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.
1 On the sides and front of the mouth, the teeth and lips form the major boundary. On the bottom, the tongue and adjacent tissues form the floor of the mouth.  The tongue is an elongated muscular organ with the top surface covered with specialized little mushroom-shaped structures called papillae.
