Nerves that connect the brain to the rest of the body and run outside the spinal cord belong to the peripheral nervous system. This system includes all nerves outside the brain and spinal cord, acting as the communication lines between the central nervous system and the limbs, organs, and senses. The central nervous system itself is made up of the brain and spinal cord, while the peripheral system carries messages to and from these centers. Within the peripheral system, the autonomic part handles involuntary functions (like heart rate and digestion) and the somatic part handles voluntary movements and sensory input. The key idea is that these nerves extend beyond the CNS to reach everything else in the body, which is why this system fits the description.
