Final answer:
The two main divisions of the nervous system are the central nervous system and the peripheral nervous system. The central nervous system consists of the brain and spinal cord, while the peripheral nervous system connects the CNS to the rest of the body. The PNS has two major subdivisions: the somatic nervous system and the autonomic nervous system.
Step-by-step explanation:
The two main divisions of the human nervous system are the central nervous system and the peripheral nervous system. The central nervous system (CNS) is composed of the brain and spinal cord, while the peripheral nervous system (PNS) connects the CNS to the rest of the body. The PNS has two major subdivisions: the somatic nervous system and the autonomic nervous system.
