==Introduction==
The oral cavity is the first section of the alimentary tract that recieves food. It provides the digestive functions of prehension, mastication and insalivation and also plays a role in the respiratory system through oral breathing when the nasopharynx is impaired.
The oral cavity or mouth, consists of accessory structures (the salivary glands), projecting structures (the teeth and tongue) and the walls enclosing the oral cavity.
==Anatomical Boundaries==
*Rostrally by lips.
*Caudally by pharynx at the level of the palatoglossal arches.
*The outer vestibule is between the teeth and jaw margins medially, to the lips and cheeks laterally and the ramus of the mandible and masseter muscle caudally.
*The oral cavity proper is inside the dental arches.
