Intramural Nerve Plexus Key to Gastrointestinal Muscle Control

Subject : Biology

Question:

The interrelated network of nerves within the gastrointestinal wall that regulates its muscular action is known as the:

A. biliary nerve plexus.

B. oligonerve plexus.

C. intramural nerve plexus.

D. bionerve plexus.

E. intestinal nerve plexus.

F. gastric nerve plexus.

Expert Verified Solution:

The correct answer is C. intramural nerve plexus. The intramural nerve plexus, often referred to as the enteric nervous system, is a complex network of nerves embedded in the walls of the gastrointestinal tract. It is responsible for coordinating the smooth muscular movements that facilitate digestion, such as peristalsis (the wave-like contractions that move food through the digestive system).

This nerve network operates independently of the central nervous system but communicates with it, playing a crucial role in controlling gastrointestinal function, including the regulation of secretions and blood flow.
