Autonomic Control. Saliva is produced and secreted by the salivary glands of the body. These glands are under the control of the autonomic nervous system, comprised of sympathetic and parasympathetic nerve fibres. Sympathetic Innervation. The sympathetic control of salivary production is via the superior cervical ganglion. There are three paired salivary glands that are responsible for the production of saliva, the submandibular glands, the sublingual glands and the parotid glands. They are all ducted, exocrine glands.

Indeed, we found that inhibition of NOS activity by NG-nitro-L-arginine methyl ester (L-NAME) or NG-monomethyl-L-arginine (L-NMMA) injected in-travenously in rats before stimulation of salivary se-cretion with methacholine (MC) signiﬁcantly inhibited the secretion of saliva. The functions of saliva fall into three general categories: digestion, lubrication, and protection. Saliva is produced in large volumes, relative to the weight of the salivary glands, by an active process. Unlike the process in the other gastrointestinal glands, the secretion of saliva is almost totally under neural control. FORMATION & SECRETION OF SALIVA The formation of saliva occurs in 2 stages.

Uniquely, both parasympathetic and sympathetic stimulation via muscarinic receptors causes increased salivation although parasympathetic activity is much more powerful. “Human Physiology” is a free online course on Janux that is open to anyone.

cells are controlled by the autonomic nervous system and upon con - traction they are believed to assist the flow of saliva by compressing the acini and the ducts and also to provide structural resilience to the parenchyma during secretion.41 Although they are contractile there is no evidence to suggest they force saliva out of acini by in-

A diet rich in carbohydrate increases the salivary amylase. Of the endocrine secretions, adrenocorticotrophic hormone lowers the sodium concentration of saliva. Significance of Double Nerve Supply: Saliva is hyposmotic at all rates of secretion, and in contrast to the other gastrointestinal (GI) secretions, the rate of secretion is almost totally under the control of the nervous system.

It is secreted by all three paired salivary glands – parotid, submandibular and sublingual.
