Quizplus · Accepted Answer

The release of secretin is not a part of the cephalic phase of gastric secretion. Secretin is released in response to the presence of acidic chyme in the duodenum, which stimulates the release of bicarbonate from the pancreas to neutralize the acid. The cephalic phase is triggered by sensory input related to the anticipation and consumption of food, leading to vagal stimulation of the gastric glands and the secretion of HCl and pepsinogen.
