Question

Quizplus · Accepted Answer

The peripheral nervous system (PNS) and central nervous system (CNS) are the two main divisions of the nervous system. The PNS consists of the nerves that extend outside of the brain and spinal cord, while the CNS includes the brain and spinal cord. Choice A is incorrect because the brain and spinal cord are both part of the CNS. Choice B is incorrect because the autonomic and somatic nervous systems are two subcategories within the PNS. Choice D is also incorrect because the parasympathetic and sympathetic nervous systems are two branches of the autonomic nervous system, which is a subdivision of the PNS.
