PHASES OF ACID SECRETION. The physiologic stimulation of acid secretion has classically been divided into three interrelated phases: cephalic, gastric, and intestinal. The cephalic phase is activated by the thought, taste, smell, and sight of food, and swallowing. It is mediated mostly by cholinergic/vagal mechanisms.

There is increased secretion of hydrochloric acid in the stomach. Cardiac stimulation increases the force at which the heart contracts and the rate at which it beats. Stimulation of H2 receptors does.

Cholinergic control of gastric acid secretion. In contrast, inhibition of nicotinic receptors with hexamethonium produced a striking potentiation of ACh stimulated secretion whilst the bethanechol elicited secretion remained unaffected. In the presence of full nicotinic receptor blockade the ACh response curve was shifted to the left sixfold,

After acute treatment of the vagus nerve with capsaicin (at the time of experimentation) maximally stimulated acid secretion was significantly reduced by about 50%. 5. Taken together, these results indicate that capsaicin‐sensitive afferent fibres contribute to the acid secretory response induced by electrical vagal stimulation in the rat.

To the Editor: Recently, Hatton et al. described a number of side effects of vagal nerve stimulator (VNS) implantation related to vagal efferent control of the gastrointestinal tract via the parasympathetic nervous system.Dyspepsia occurring in 12.6% can be explained by the action of the vagus nerve, which stimulates increased gastric acid secretion as well as promotes gastric.

The “wandering nerve” helps us go into relaxation because it gets stimulated by our deep breathing. Scientists call it the Vagus nerve — the longest. It helps release tears, saliva and stomach acid.

Sep 22, 2017. This review is focused on gastric acid secretion, a process centered on the parietal. Vagal stimulation of acid secretion has long been known.

Though it seems paradoxical, sometime people with GERD have low stomach acid, not high. It is a complicated physiology related to neurotransmitters and hormones in addition to another thing that helps.

Stimulation of Gastric Acid Secretion. Parietal Cells of the Oxyntic Glands Are the Only Cells That Secrete Hydrochloric Acid. Theparietal cells, located deepin the oxyntic glands of the main body of the stomach, are the only cells that secrete hydrochloric acid.As noted earlier, the acidity of the fluid secreted by these cells can be very great, with pH as low as 0.8.
