Question

Auerbach’s plexus and Meissner’s plexus are located in the:

• A. Muscularis and submucosa layer respectively
• B. Submucosa and muscularis layer respectively
• C. Serosa and mucosa respectively
• D. Submucosa and mucosa respectively

Answer 1

The correct option is A Muscularis and submucosa layer respectively

Gastrointestinal tract is divided into four layers such as mucosa, submucosa, muscularis and serosa.

The myenteric plexus or Auerbach’s plexus is in the muscularis layer of alimentary canal.

An inner plexus called the submucosal plexus or Meissner’s plexus lies in the submucosa.

Mucosa is the innermost layer and functions in absorption and secretion.

Serosa is the outermost layer and is made up of a thin mesothelium.
So, the correct answer is option 'a'.
