Quizplus · Accepted Answer

The central nervous system (CNS) consists of the brain and spinal cord, while the peripheral nervous system (PNS) includes all the neural structures outside of the CNS, including nerves, ganglia, and sensory receptors. Therefore, choice A is the correct answer. Choice B is incorrect because the autonomic nervous system is actually a part of the peripheral nervous system. Choice C is incorrect because the sympathetic nervous system is a part of the autonomic nervous system, which is a division of the peripheral nervous system. Choice D is incorrect because the somatic nervous system is a subdivision of the peripheral nervous system, which is distinct from the central nervous system.
