The correct answer is: D) secretin
Gastric secretion is highly regulated whether its secretion should be increased (when food is eaten) or decresed (as the stomach empties). Secretion is controlled by the nervous system and endocrine system that work together. There are three phases of gastric secretory control:
Cephalic-by the brain
Gastric-by the stomach itself
Intestinal- by the small intestine
All of three can work simultaneously.
Secretin is released by duodenal enteroendocrine cells and it stimulates the pancreas and gall bladder, but also suppresss gastric secretion and motility. Secretion of the secretin is stimulated by the chime and it is the part of intestinal phase.
<span>Many of the sensory and motor functions are controlled by the central nervous system and the brain. An example of this would be grabbing a hot pot from the stove. Your brain sends a signal to your hand to tell it to grab the pot. When you grab it your sensory nerves detect that the pot is hot and is burning your hand. The signal it sends back to the brain is one that there is pain and to release the pot.</span>
