Nervous System handouts

The document provides an overview of the nervous system, which is divided into the central nervous system (brain and spinal cord) and peripheral nervous system. The peripheral nervous system consists of the somatic nervous system, which controls voluntary functions, and the autonomic nervous system, which controls involuntary functions. The autonomic nervous system further divides into the sympathetic and parasympathetic nervous systems, with the sympathetic system using adrenaline and the parasympathetic system using acetylcholine.
