  Amygdala distress signal to the Hypothalamus --> Hypothalamus stimulates the sympathetic branch of the ANS -->stimulates the Adrenal Medulla---> secretes adrenaline/noradrenaline --. physiological changes --> parasympathetic cools down
• SAM?


  triggered in response to acute stress
• HPA?


  hypothalamus. anterior pituitary> ACTH> adrenal cortex> Cortisol> effects after 20 minutes
• Fuels?


  provides body with a stream of fuel > calms down effects of adrenaline and noradrenaline gives individuals with enough energy for stressor.
• supress immune system?


  ensure resources are focused on dealing with the stressor
