Question

The reflex in which there is inhibition of gastric emptying when there is acid and hypertonic solution in the duodenum?

• A. Enterogastric
• B. Gastroileal
• C. Gastrocolic
• D. Myenteric

Answer 1

The Correct Option is A

The correct reflex involved in the inhibition of gastric emptying when there is acid and hypertonic solution in the duodenum is known as the Enterogastric reflex.

This reflex is a physiological mechanism that serves to slow down the gastric emptying process in response to stimuli such as high acidity or hyperosmolarity in the duodenum. When the duodenal receptors detect such conditions, signals are sent to the stomach to inhibit gastric motility and reduce the secretion of gastric acid, thereby delaying the transfer of stomach contents into the small intestine until it is better prepared to process them.

Reflex	Description
Enterogastric	Inhibits gastric emptying in response to acid and hypertonic solutions in the duodenum.
Gastroileal	Stimulates ileal activity and relaxation of the ileocecal valve after a meal.
Gastrocolic	Initiates colon motility following stomach filling.
Myenteric	Coordinates gut motility through the enteric nervous system.
