What is the difference between the central and peripheral nervous systems?

The nervous system is the complex network of nerve cells that transmit signals between different parts of the body. The nervous system can be divided into two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord, while the PNS is composed of all the other nerves in the body.

The CNS acts as the control center for the body, receiving and interpreting sensory information and sending out motor commands to the PNS. The PNS carries signals between the CNS and the rest of the body, allowing for communication and coordination between different parts of the body.

The main difference between the CNS and PNS is their location within the body. The CNS is located within the skull and spinal column, while the PNS is located outside of the CNS. Additionally, the CNS is composed of neurons and glial cells, while the PNS is composed of nerves and ganglia.
