Quizplus · Accepted Answer

The major divisions of the nervous system are the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord, while the PNS includes all the nerve fibers that extend from the spinal cord and brain to various parts of the body. Therefore, B is the correct answer. A is incorrect because the somatic and autonomic systems are part of the PNS. C is incorrect because it ignores the PNS. D is incorrect because the peripheral nervous system is a subset of the PNS, and the autonomic system is part of the PNS.
