  1. WHS AP Psychology Unit 4: Biological Psychology Essential Task 4-5b:Describe the subdivisions and functionsof the peripheralnervous system: A. Somatic Nervous System B. Autonomic Nervous System i. Sympathetic Nervous System (Fight or Flight) ii. Parasympathetic Nervous System (Rest and Digest)

  2. Endocrine System Evolutionary Building Blocks Genetics Biological Psychology Neurons Neurotransmitters Nervous System Central Nervous System Peripheral Nervous System Motor Sensory Spinal Cord Brain Autonomic We are here Somatic Brain Imaging Sympathetic Parasympathetic

  3. Essential Task 4-5b: Outline A. Somatic Nervous System B. Autonomic Nervous System • i. Sympathetic Nervous System (Fight or Flight) • ii. Parasympathetic Nervous System (Rest and Digest)

  4. The Somatic Nervous System • Consists of neurons that communicate between the body and the brain • Motor Neurons • Neurons that carry messages from the spinal cord or brain to muscles and glands

  5. The Autonomic Nervous System • Sympathetic division • Most active when you are angry, afraid, or aroused • Increases heart rate and breathing • Stops digestion • “Fight-or-flight”

  6. SNS = Evolutionary Byproduct

  7. Scared Bros

  8. Hold me!

  9. Congo line of fear

  10. Swag gone scared

  11. Even Flannel Bros have an SNS response

  12. Connector Bros

  13. I’m not really here to protect you. ( I just happen to be in front)

  14. Fight, Flight and Freeze

  15. The better to see you with my dear

  16. The Autonomic Nervous System • Parasympathetic division • Calms body • Produces effects opposite to those of the sympathetic division • Reduces heart rate and breathing • Restores digestion • “Rest and Digest”

  17. The Hypothalamus Has Central Control of the ANS • When someone experiences a stressful event, the amygdala, an area of the brain that contributes to emotional processing, sends a distress signal to the hypothalamus. This area of the brain functions like a command center, communicating with the rest of the body through the nervous system so that the person has the energy to fight or flee. • The hypothalamus is involved in the coordination of ANS responses • One section of the hypothalamus seems to control many of the "fight or flight" responses; another section favors "rest and digest" activities
