==Introduction==

The oral cavity is the first section of the alimentary tract that recieves food. It provides the digestive functions of prehension, [[Mastication|mastication]] and insalivation and also plays a role in the [[Cardiorespiratory System Overview - Anatomy & Physiology|respiratory system]] through oral breathing when the nasopharynx is impaired. The oral cavity or mouth, consists of accessory structures (the [[Salivary Glands - Anatomy & Physiology|salivary glands]]), projecting structures, (the [[:Category:Teeth - Anatomy & Physiology|teeth]] and the [[Tongue - Anatomy & Physiology|tongue]]) and the walls enclosing the oral cavity.

Inside the dental arches, the palate borders dorsally and the [[:Category:Teeth - Anatomy & Physiology|teeth]], gums and jaw margins laterally. The [[Tongue - Anatomy & Physiology|tongue]] margins ventrally. The size can be altered by raising or lowering the [[Tongue - Anatomy & Physiology|tongue]] and the floor of the oral cavity when the mouth is closed.

==Origin and Innervation==

The oral cavity originates from ectoderm. It is innervated by the '''trigeminal nerve''' ([[Cranial Nerves - Anatomy & Physiology|CN V]]).
