Question

Which of the following systems causes inhibition of gastrointestinal tract activity?

• A. Parasympathetic system
• B. Sympathetic system
• C. Central nervous system
• D. None of the above

Answer 1

The correct option is B Sympathetic system

Sympathetic system is a part of the autonomic nervous system. It generally inhibits the activity of the gastrointestinal tract such as inhibition of gastrointestinal secretion, motor activity, contraction of gastrointestinal sphincters and blood vessels.

The parasympathetic system is a part of the autonomic nervous system. It primarily stimulates the body’s “rest and digest” response such as enhancing the activity of most gastrointestinal functions.

The central nervous system helps in learning and voluntary control of movement.
