The first being the central nervous system (cns), located within the brain and spinal cord which is responsible for mental processing, understanding and organizing information which will better help the person adapt to its environment and the creatures around them. Then the second nervous system is the peripheral nervous system which is located outside of the brain and spinal cord; is responsible for carrying information to and from the central nervous system. The peripheral nervous system has four divisions: somatic nervous system, also called skeletal nervous system (controls voluntary movements of the body as well as reflexes), autonomic nervous system (controls involuntary life functions: heart beat, breathing, eye pupil dilation, digestion, ect.), sympathetic nervous system (causes arousal of involuntary life functions: increase heart rate, faster breathing, enlarging eye pupil, etc.), and parasympathetic nervous system (causes calming of involuntary life functions: decreased heart rate, slowering of breath, pupils constrict, etc), (Sanderson
