Glándulas Salivares - Resumen - Anatomía & Fisiología
Salivary glands are present in the mejilla, lengua, labios, oesophagus, paladar blando and faringe but the major salivary glands are located further away from the cavidad oral and function through connective ducts.
Saliva provides digestive enzymes, is a route of excretion of substances which accumulate on the dientes and provides lubricative and also cleansing functions. Salivary glands can produce a serous secretion, a 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 (CN VII) and glossopharyngeal (CN XI) then into branches of the trigeminal nerve (CN V). The flow of salivary fluid increases and vasodilation occurs.
Saliva is mainly water and contains amylase for carbohydrate digestion, salt- mainly sodium bicarbonate, mucin, electrolytes, antimicrobial agents and lingual lipase.
