Question

the somatic nervous system controls ____ activity while the autonomic nervous system controls ____. a skeletal muscle; conscious activity b cardiac muscle; skeletal muscle c skeletal muscle; visceral activity d cardiac muscle; smooth muscle e smooth muscle; skeletal muscle

Explanation:

The somatic nervous system is responsible for voluntary movements, which involve skeletal muscles. The autonomic nervous system controls involuntary functions like visceral (internal organ - related) activities. Option A is incorrect as the autonomic nervous system does not control conscious activity. Option B is wrong because the somatic nervous system does not control cardiac muscle (which is under autonomic control). Option D and E are incorrect as smooth muscle (like in blood vessels, digestive tract) and cardiac muscle are under autonomic control, while skeletal muscle is under somatic control.

Answer:

C. skeletal muscle; visceral activity
