Which division of the nervous system consists of the brain and spinal cord?

The central idea is that the nervous system is split into the brain and spinal cord (the central nervous system) and everything outside them (the peripheral nervous system). The brain and spinal cord act as the body's main control center, processing information, making decisions, and sending signals to the rest of the body. The brain processes complex thoughts and sensations, while the spinal cord transmits messages between the brain and limbs or organs. The other divisions lie outside the CNS. The somatic nervous system is the part of the peripheral nervous system that carries sensory information to the CNS and controls voluntary muscles. The autonomic nervous system, another part of the peripheral system, regulates involuntary functions like heart rate and digestion and includes its own sympathetic and parasympathetic branches. The peripheral nervous system as a whole encompasses these pathways that connect the CNS to the body. So, the division that consists of the brain and spinal cord is the central nervous system.
