Which of these inhibits secretion and motility of the stomach?
a. enterogastric reflex
b. parasympathetic stimulation
c. gastrin
d. intrinsic factor
e. distention of stomach wall
Answer: A
Feedback : The enterogastric reflex, consisting of a local reflex and a reflex integrated within the medulla oblongata, inhibits gastric secretion and motility. It results from distension of the duodenal wall, presence of irritating substances in the duodenum, reduced pH and hypertonic or hypotonic solutions in the duodenum.
