NEET PG DENTAL EXAM

Detailed explanation-1: -Parasympathetic stimulation evokes a copious flow of saliva. In contrast, sympathetic stimulation produces either a small flow, which is rich in protein, or no flow at all.

Detailed explanation-2: -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.

Detailed explanation-3: -All salivary glands are supplied by cholinergic parasympathetic nerves which release acetylcholine that binds to M3 and (to a lesser extent) M1 muscarinic receptors, evoking the secretion of saliva by acinar cells in the endpieces of the salivary gland ductal tree.

Detailed explanation-4: -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.
