Question

The plexus that mainly controls the gastrointestinal movements is:

• A. Meissner’s plexus
• B. Auerbach’s plexus
• C. Submucosal plexus
• D. None of the above

Answer 1

The correct option is B Auerbach’s plexus

A plexus is a branching network of vessels or nerves. An outer plexus lying in the muscularis layer of alimentary canal is called the myenteric plexus or Auerbach’s plexus. The myenteric plexus controls mainly the gastrointestinal movements.

An inner plexus, called the submucosal plexus or Meissner’s plexus lies in the submucosa of the gastrointestinal tract. The submucosal plexus controls mainly gastrointestinal secretion and local blood flow.
