There is a lot to learn about the nervous system and the pathologies associated with it. What we do know is that there are two nervous systems in the human body and they relate to each other. The first is the central nervous system, which includes the brain and the spinal cord. The second nervous system, known as theperipheral nervous system, contains all the nerves in the body that lie outside of the spinal cord and brain. These two systems communicate with each other to make sure our body parts, such as our fingers, can send signals to the central nervous system for processing in our brains.

Can you see the difference in the two nervous systems? The peripheral nervous system includes all the nerves that go from the skin, muscle, and organs to the spinal cord and eventually the brain. However, the central nervous system is composed of the brain and spinal cord.
