• What does SSRI stand for?

  Selective Serotonin Reuptake Inhibitor
• What is the role of the autonomic nervous system?

  It regulates involuntary bodily functions
• How are messages passed around the nervous system?

  Through neurons via electrical impulses
• What are the two main divisions of the nervous system?

  • Central Nervous System (CNS)
  • Peripheral Nervous System (PNS)
• What are the two branches of the autonomic nervous system?

  • Sympathetic Nervous System
  • Parasympathetic Nervous System
• What happens to your body when you see your crush nearby?

• What physiological changes occur during a fearful situation?

  Pupils dilate and muscles tense
• What is the fight or flight response?

• What hormone is released by the pituitary gland during the fight or flight response?

  ACTH (Adrenocorticotropic Hormone)
• What is the role of adrenaline in the fight or flight response?

  It initiates physiological changes like increased heart rate and energy supply
• What happens after the scary event has ended in terms of the nervous system response?

  The parasympathetic nervous system restores the body to its normal state
• What are the negative consequences of repeated activation of the sympathetic nervous system?

  It can lead to physical damage to blood vessels and heart disease
• What are three features of the fight or flight response?

  • Increases heart rate
  • Releases adrenaline
  • Prepares the body for action
• What physiological changes occur during the fight or flight response?

  • Increased heart rate
  • Increased blood pressure
