Question

Quizplus · Accepted Answer

The central nervous system consists of the brain and spinal cord, therefore the correct answer is C. Choice A is incorrect because autonomic nerves are part of the peripheral nervous system. Choice B is partially correct, as the brain and spinal cord are part of the central nervous system, but peripheral nerves are part of the peripheral nervous system. Choice D is incorrect because it divides the nervous system into sensory and motor, which are functional divisions rather than anatomical divisions, and it does not include the spinal cord.
