Motility and peristalsis · Physiology

Which of the following best describes the 'Vagovagal reflex' in the context of gastric motility?

  1. Reflex that triggers vomiting after ingesting toxins
  2. Relaxation of the stomach fundus as food enters
  3. Contraction of the pylorus when acid reaches the duodenum
  4. Urge to defecate after consuming a large meal
Show answer and explanation

Correct answer: Relaxation of the stomach fundus as food enters

Receptive relaxation of the stomach is a vagovagal reflex where stretching of the esophagus and stomach causes the fundus to relax. This allows the stomach to accommodate a large volume of food with minimal increase in intragastric pressure.
