Question

Choose the type of nervous system and type of muscle supplying visceral organs

• A. Sympathetic nervous system, voluntary
• B. Sympathetic nervous system, involuntary
• C. Parasympathetic nervous system, involuntary
• D. Both sympathetic and parasympathetic nervous systems, involuntary

Answer 1

The correct option is D Both sympathetic and parasympathetic nervous systems, involuntary

The blood is supplied into visceral organs by both SNS (sympathetic nervous system) and PNS (parasympathetic nervous system) involuntarily. The sympathetic fibres increase the rate and force of heart beat, constrict most blood vessels and raise the arterial blood pressure. It controls the glands and smooth muscle of all the internal organs (viscera) .

Hence, the correct answer is (D)
