Stress Outline

So Im a moron and still having trouble getting the outline under class notes so I decided to go ahead and post it on here, but hopefully well have the classnotes area resolved soon.

Stress

  • How has stress been defined? What is stress?
  • How is the stress response adaptive?
  • Explain the phases of stress. (Hint: think Selye)
  • Explain the different categories of stress. What are the different categories of stressors? Give examples from each category.
  • What systems are involved in an acute stress response? How are they anatomically and physiologically organized? What are the mechanisms by which the stress response occurs?
  • What hormones/ receptors are involved in the stress response? What types of feedback mechanism are involved in the stress response?
  • What systems/ processes are affected by the stress response? Physiologically speaking, how are they affected? (Example: heart rate increases→ what is the physiologically mechanism for this)
  • What happens to homeostatic controls during the stress response?
  • How is homeostasis restored following a stress response? (Give examples.)
  • Describe disorders of a maladaptive stress response. What is current working theory for the physiologically explanation of these disorders?
  • What other factors, besides physiology, would affect an individual’s stress response?
