Sympathetic Innervation
Sympathetic stimulation results in the release of noradrenaline, which acts upon alpha- and beta-adrenergic receptors. This results in the following effects: Decreased production of saliva by acinar cells. Increased protein secretion.
Does the sympathetic nervous system increased salivation?
The parasympathetic system turns up the flow of saliva by releasing a chemical, acetylcholine, which stimulates the glands to make more saliva. ... The sympathetic nerve supply produces predominantly thicker mucous saliva mainly by the sublingual and partly the submandibular glands.
Is salivation sympathetic or parasympathetic?
The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.
