WHAT’S THE DIFFERENCE . . .

. . . between the central nervous system and the peripheral nervous system?

THE nervous system is a network of cells that transmit signals between the brain and the rest of the body. The central nervous system refers to nerve cells in the brain and spinal cord, controllin­g thoughts, desires and emotions as well as breathing, heart rate, body temperatur­e and the release of some hormones. The peripheral nervous system contains nerves that branch out from the brain and spinal cord, connecting the central nervous system to the organs, limbs and skin, and controllin­g actions such as movement, digestion and sexual function, as well as reactions to physical sensations.
