under control of the autonomic nervous system parasympathetic: dominant regulator and intiates and maintains salivary secretions a) acetylcholine released from parasympathetic nerves binds to muscarinic receptors: increases IP3 and intracellular Ca2+ to increase saliva secretion) sympathetic: norepinephrine (NE) binds to alpha or beta receptors
Saliva in the mouth is a biofluid produced mainly by three pairs of major salivary glands--the submandibular, parotid and sublingual glands--along with secretions from many minor submucosal salivary glands.
