Regulation of Secretion of Saliva: Salivary secretion regulation is brought about by both neural and the hormone (hormonal) mechanisms.

Shannon IL, Suddick RP, Dowd FJ Jr. PMID: 4601379 [PubMed - indexed for MEDLINE] 2020-12-19 · Many taste stimuli, especially the sour taste (caused by acids), elicit copious secretion of saliva—often 8 to 20 times the basal rate of secretion. Also, certain tactile stimuli, such as the presence of smooth objects in the mouth (e.g., a pebble), cause marked salivation, whereas rough objects cause less salivation and occasionally even inhibit salivation. Saliva is secreted by three glands which produce saliva of slightly different composition. The parotid glands only generate a serous secretion whereas the submaxillary glands and the sublingual glands generate both serous and mucinous fluid. 2020-11-30 · Production of Saliva.

udg. Certain drugs like pilocarpine and cevimeline can stimulate saliva production and secretion. However, these drugs will only work if the salivary gland is not damaged. Furthermore it will only provide symptomatic relief associated with hyposalivation and the root cause has to still be identified and treated. The first part of this review article provides an updated insight into our understanding of salivary gland structure, the neural regulation of salivary gland secretion, the mechanisms underlying the formation of saliva, the various functions of saliva and factors that influence salivary secretion under normal physiological conditions.

The secretion of saliva is markedly diminished in states of anxiety and depression. The consequent dry mouth interferes with speech, which becomes thick and indistinct. In the absence of the cleansing action of saliva, food debris persists in the mouth and stagnates, especially around the base of the… saliva secretion varies between 800- 1500 ml / day or 1.0 to 3.0 ml / minute with a pH in the range of 6-7 for unstimulated whole saliva.(5,8) Unstimulated saliva is the mixture of secretions which enters themouth in absence of exogenous It reflects the basal salivary flow rate, present in the oral cavity for about 24 hours a day. In salivary Saliva and mucoid secretions form a vital part of a patient’s barrier immune system.4 Sialorrhoea and its symptoms Sialorrhoea is an inconsistently used term most commonly describing excessive serous saliva in the mouth that can result from hypersecretion of saliva, anatomical abnormalities or facial–bulbar weakness.
