The myenteric plexus is found between which layers?

The myenteric plexus is found between which layers?

• A. Between the external longitudinal and circular smooth muscle layer
• B. Between the mucosa and submucosa
• C. Within the serosa
• D. In the submucosa

Answer: (A)

The myenteric plexus coordinates GI motility and sits in the muscularis externa, between the inner circular muscle layer and the outer longitudinal muscle layer. This placement lets it regulate the rhythmic contractions that move content along the gut. In contrast, the submucosal (Meissner) plexus lies in the submucosa between the mucosa and circular muscle and mainly controls secretions and local blood flow. So the correct description is between the two muscle layers of the muscularis externa.
