                              1. Sympathetic NS
                                1. "Gas" "Accelerates"
                                  1. Prepares for "fight-or-flight"
                                    1. e.g., increased HR, pupil dilation, conversion of energy stores (fat and glycogen) to glucose
                                2. Parasympathetic NS
                                  1. "Brakes" "Deactivates"
                                    1. Responds to SNS creating states of relaxation
                                      1. e.g., decreased HR, activation of digestion & elimination, conversion of glucose to energy stores (glycogen & fat)
                                    2. Regulates Involuntary Movements
                                      1. e.g., Digestion, Respiration, Heartbeat & Autonomic Arousal
                                    3. Somatic Nervous System (SNS)
                                      1. Voluntary Movement
                                        1. Relays signals from senses
                                          1. Controls Skeletal Muscles
                                      2. Afferent Nerves - "Sensory or Receptor" nerves, carry info from SENSE ORGANS to CNS
                                        1. Efferent Nerves - "Motor or Effector" nerves, carry info from CNS to MUSCLES & GLANDS
