Meissner's (submucous) plexus lies in which layer of the gut wall?
- A In the submucosa ✓
- B Between the longitudinal and circular muscle layers
- C Between the muscularis externa and serosa
- D In the lamina propria beneath the epithelium
Correct answer: A. In the submucosa
Explanation
Meissner's submucous plexus lies in the submucosa and regulates local secretion and blood flow. Auerbach's myenteric plexus lies between the longitudinal and circular muscle layers and controls motility. Confusing the two layers is a common error. Ref: Gray's Anatomy, 42nd ed, p 1143.
