The nervous system of the human is broken down into two categories. We have the central nervous system which contains the brain and the spinal cord and the peripheral nervous system. Now, the peripheral nervous system is made up of neurons and support cells that are found outside of the central nervous system outside of the brain and a spinal cord. So the peripheral nervous system system is further divided into the autonomic nervous system and the somatic nervous system. So in this lecture, we're going to focus on the somatic nervous system. Now, the somatic nervous system consists of two divisions.
