Question

Quizplus · Accepted Answer

The peripheral nervous system is made up of all the nerves that are outside the central nervous system, which includes the brain and spinal cord. The two main divisions of the peripheral nervous system are the somatic nervous system, which controls voluntary movements and sensory information, and the autonomic nervous system, which controls involuntary processes such as heart rate, digestion, and blood pressure. Therefore, choice A is the correct answer. Choice B is incorrect because the sympathetic and parasympathetic systems are subdivisions of the autonomic nervous system. Choice C is incorrect because afferent and efferent refer to the direction of nerve signals, not different systems. Choice D is incorrect because reticular and limbic are types of brain structures, not divisions of the peripheral nervous system.
