The [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]] is drained by numerous salivary glands. The saliva secreted keeps the mouth moist and facilitates [[Mastication|mastication]] by lubricating the passage of the bolus.

Salivary gands are present in the [[Cheeks|cheek]], [[Tongue - Anatomy & Physiology|tongue]], [[Lips|lips]], [[Oesophagus - Anatomy & Physiology|oesophagus]], [[Soft Palate|soft palate]] and [[Pharynx - Anatomy & Physiology|pharynx]] but the major salivary glands are located further away from the [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]] and function through connective ducts.

Saliva provides digestive enzymes, is a route of excretion of substances which accumulate on the [[:Category:Teeth - Anatomy & Physiology|teeth]] and provides lubricative and also cleansing functions. Salivary glands can produce a [[Serous Salivary Gland - Anatomy & Physiology|serous]] secretion, a [[Mucous Salivary Gland - Anatomy & Physiology|mucous]] secretion or both.

The salivary glands are innervated by '''sympathetic'''- Vasoconstriction occurs and the flow of saliva is decreased.

   −
The salivary glands are also innervated by '''parasympathetic''' (most important)- They travel from the brainstem by the facial ([[Cranial Nerves - Anatomy & Physiology|CN VII]]) and glossopharyngeal ([[Cranial Nerves - Anatomy & Physiology|CN XI]]) then into branches of the trigeminal nerve ([[Cranial Nerves - Anatomy & Physiology|CN V]]). The flow of salivary fluid increases and vasodilation occurs.
