Communication between the central nervous system and the rest of the body is facilitated by the peripheral nervous system, which includes cranial nerves from the brain and spinal nerves from the spinal cord.

Communication between the central nervous system (CNS) and the rest of the body is facilitated through the peripheral nervous system (PNS). The PNS comprises sensory neurons that transmit information from sensory receptors to the CNS and motor neurons that convey commands from the CNS to muscles and glands. These neurons form intricate networks connecting the brain and spinal cord to various tissues. Neurotransmitters, chemical messengers, transmit signals across synapses, facilitating rapid communication. Sensory input informs the CNS, enabling perception, while motor output directs voluntary and involuntary actions. This dynamic interplay ensures coordinated responses and maintains homeostasis in the body.
