==Introduction==
 
 
 
The [[Oral Cavity Overview - Anatomy & Physiology|oral cavity]] is drained by numerous salivary glands.  The saliva secreted keeps the mouth moist and facillitates [[Mastication|mastication]] by lubricating the passage of the bolus.
 
 
 
Salivary gands are present in the [[Cheeks - Anatomy & Physiology|cheek]], [[Oral Cavity - Tongue - Anatomy & Physiology|tongue]], [[Lips - Anatomy & Physiology|lips]], oesophagus, [[Soft Palate - Anatomy & Physiology|soft palate]] and 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 [[Tooth Anatomy - Anatomy & Physiology|teeth]] and provides lubricative and also cleansing functions.
 
 
 
==Types of Salivary Glands==
 
 
 
*[[Parotid]]
 
 
 
*[[Mandibular]]
 
 
 
*[[Sublingual]]
 
 
 
*[[Zygomatic]]
 
 
 
*[[Labial]]
 
 
 
*[[Lingual]]
 
 
 
*[[Buccal]]
 
 
 
*[[Palatine]]
 
 
 
 
 
==Innervation==
 
 
 
*Sympathetic
 
    -Vasoconstriction occurs
 
    -Flow of saliva is decreased
 
 
 
*Parasympathetic (most important)
 
    -Travel from the brainstem by the facial (CN VII) and glossopharyngeal (CN IX) then into branches of the trigeminal nerve (CN V)
 
    -Flow of salivary fluid increases
 
    -vasodilation occurs
