The central nervous system consists of the brain and the spinal cord and the peripheral nervous system consist of all the nerves that branch off of the brain and spinal cord. With those systems we have the sensory division and the motor division also stemming from those we have the somatic and autonomic nervous system. For all these systems to work together in unison are cells called neurons. Neurons structure includes the cell body, dendrites which picks up messages and the axons which send…show more content…
