2. The Organization of the Nervous System Organization of the Nervous System

3. The central nervous system Brain Spinal Cord

4. The central nervous system Two important areas Reward System Hypothalamus

5. 5 The Peripheral Nervous System –Somatic nervous system: Controls the movement of skeletal muscles or transmits somatosensory information to the central nervous system. –Autonomic nervous system: Controls the body’s vegetative functions. “fight or flight” response Sympathetic division: –Controls functions that accompany arousal and expenditure of energy. Parasympathetic division: –Controls functions that occur during a relaxed state.
