The __________ division carries signals to the smooth muscle in the large intestine.
ololo11 [35]

Answer:

Visceral motor

Explanation:

Peripheral nervous system is divided further into visceral and somatic nervous system. Somatic nervous system controls the skeletal muscles, joints and tendons. Visceral nervous system controls cardiac muscles, glands and smooth muscles.

Large intestine has smooth muscles so it is controlled by the visceral nervous system. It has further two divisions, sensory and motor. Sensory division carries signals from the muscle to the central nervous system whereas motor division carries signals from the central nervous system to the muscle which cause an action. Hence, visceral motor division carries signals to the smooth muscle in the large intestine.
