Fight or Flight Flashcards
What happens in step 1 of the sympathomedullary pathway?
An event is perceived as an acute stressor by the brain and the hypothalamus is activated
What happens in step 2 of the sympathomedullary pathway?
The sympathetic branch of the autonomic nervous system is activated
What happens in step 3 of the sympathomedullary pathway?
The adrenal medulla is stimulated and it releases adrenaline and non adrenaline
What happens in step 4 of the sympathomedullary pathway?
These cause blood pressure, heart rate and sweat production to increase, the body is then ready for fight or flight
What happens in step 1 of the hypothalamic pituitary adrenal pathway?
An event is perceived as a chronic stressor by the brain and the hypothalamus is activated
What happens in step 2 of the hypothalamic pituitary adrenal pathway?
The pituitary gland is activated which then releases the stress hormone ACTH (adrenocorticotrophic hormone)
What happens in step 3 of the hypothalamic pituitary adrenal pathway?
This stimulates the adrenal cortex to release cortisol
What happens in step 4 of the hypothalamic pituitary adrenal pathway?
These hormones suppress the immune system and increase energy levels
