The function of our visceral organs is controlled by

Sympathetic and parasympathetic neural system

Explanation:

Visceral organs are the internal organs present in chest or abdomen.

Sympathetic and parasympathetic neural system controls the functioning of the visceral organs of the body.

Somatic neural system is associated with peripheral nervous system and has no role in regulation of the visceral organs.

Central nervous system is associated with brain and spinal cord and has no control over visceral organs.
