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 oral tongue is the part you see when you poke your tongue out at someone. This is the front two thirds of your tongue. Cancers that develop in this part of the tongue come under a group of cancers called mouth (oral) cancer. The base of the tongue is the back third of the tongue. This part is very near your throat (pharynx).
