What are not important as a stimulus in the gastric phase of gastric secretion?

During the gastric phase of gastric secretion, stimuli that are not important include the presence of food in the mouth and the sight or smell of food, which primarily activate the cephalic phase. Additionally, factors like emotional stress or anxiety, while they may influence overall digestion, do not play a direct role in stimulating gastric secretion during this phase. The gastric phase mainly relies on the distension of the stomach and the presence of peptides and amino acids in the stomach.
