Solution
The correct option is A Gastrin The gastrin hormone is secreted by the pyloric stomach located adjacent to the duodenum. This hormone stimulates the gastric glands to release gastric juice and regulates the movement of the stomach.
Secretin is produced by the small intestinal mucosa region. It may inhibit the gastrin secretion and stomach movement. Both enterogastrone and duocrinin hormones are released from duodenal mucosa. Enterogastrone regulates gastric contraction and inhibits production of gastric juice. Duocrinin stimulates the viscous mucosa secretion from Brunner's gland into the intestinal juice.
