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.

==Innervation==

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

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.

The flow of salivary fluid increases and vasodilation occurs.  

The main nerves are the '''occulomotor''' ([[Cranial Nerves - Anatomy & Physiology|CN III]]), '''facial''' ([[Cranial Nerves - Anatomy & Physiology|CN VII]]), '''glossopharyngeal''' ([[Cranial Nerves - Anatomy & Physiology|CN IX]]) and '''vagus''' ([[Cranial Nerves - Anatomy & Physiology|CN X]]).
