| | | | |
| − | The [[Cavidad Oral - Resumen - Anatomía & Fisiología|cavidad oral]] 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 glands are present in the [[Mejillas|mejilla]], [[Lengua - Anatomía & Fisiología|lengua]], [[Labios|labios]], [[Oesophagus - Anatomía & Fisiología|oesophagus]], [[Paladar Blando|paladar blando]] and [[Faringe - Anatomía & Fisiología|faringe]] but the major salivary glands are located further away from the [[Cavidad Oral - Resumen - Anatomía & Fisiología|cavidad oral]] and function through connective ducts.
| |
| − | | |
| − | Saliva provides digestive enzymes, is a route of excretion of substances which accumulate on the [[:Categoría:Dientes - Anatomía & Fisiología|dientes]] and provides lubricative and also cleansing functions. Salivary glands can produce a [[Serous Salivary Gland - Anatomía & Fisiología|serous]] secretion, a [[Mucous Salivary Gland - Anatomía & Fisiología|mucous]] secretion or both.

| − | ==Innervation==
| |
| − | | |
| − | 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 ([[Nervios Craneales - Anatomía & Fisiología|CN VII]]) and glossopharyngeal ([[Nervios Craneales - Anatomía & Fisiología|CN XI]]) then into branches of the trigeminal nerve ([[Nervios Craneales - Anatomía & Fisiología|CN V]]). The flow of salivary fluid increases and vasodilation occurs.
| |
| − | | |
| − | The main nerves are the '''occulomotor''' ([[Nervios Craneales - Anatomía & Fisiología|CN III]]), '''facial''' ([[Nervios Craneales - Anatomía & Fisiología|CN VII]]), '''glossopharyngeal''' ([[Nervios Craneales - Anatomía & Fisiología|CN IX]]) and '''vagus''' ([[Nervios Craneales - Anatomía & Fisiología|CN X]]).

| |
| − | | |
| − | Saliva is mainly water and contains amylase for carbohydrate digestion, salt- mainly sodium bicarbonate, mucin, electrolytes, antimicrobial agents and lingual lipase.
