What is the Nervous System?
The nervous system is the mission control of the body. Almost all animals, except sponges, have a nervous system because it is necessary to perform any bodily functions. The nervous system houses many specialized cells not found anywhere else in the body. Most of these cells are neurons, when bundled together they become nerves. Nerves are pathways that transmit electrochemical signals from one part of your body to another. The entire nervous system is undeniably complicated, however, it is a well organized bureaucracy. The two main departments are the central nervous system (CNS) and peripheral nervous system (PNS). The central nervous system, all the nerves inside your brain and spinal cord, is responsible for analyzing and interpreting all the data that the peripheral nervous system, all of the nerves outside of your brain and spinal cord, collects. Once the central nervous system makes a decision about the data it sends a signal back through to the peripheral nervous system where the action will be performed.
