How is gastric secretion regulated?

How is gastric secretion regulated?

Gastric secretion is finely regulated by neural, hormonal, and paracrine pathways. During ingestion of a meal, the pathways can be activated by stimuli originating in the brain or stimuli originating in the stomach, such as mechanical stimulation (eg, distension) or chemical stimulation (eg, protein).

Can gastric secretion be stimulated before food enters the mouth?

Gastric secretion can be stimulated before food has entered the mouth. Vagus stimulation of the stomach results in decreased secretion of gastric juice. The presence of food in the stomach prevents hormonal control of gastric secretion. Gastric secretion is enhanced by very low pH (below a pH of 2).

What hormones or Paracrines inhibit gastric secretions?

Gastrin also exerts trophic effects on various tissues, including the gastric and intestinal mucosa. The main inhibitor of acid secretion is somatostatin. Somatostatin, acting via ssTR2 receptors, exerts a tonic paracrine inhibitory influence on the secretion of gastrin, histamine, and acid secretion.
