Biopsych - fight or flight response Flashcards
What branch of the nervous systems mainly control fight or flight
Sympathetic NS
What is the role of the parasympathetic NS in fight or flight
Maintains and conserves body energy and functions
What is the role of the sympathetic NS in fight or flight
Prepares body to expand energy for fight or flight
What area of the brain is activated when a stressor appears
Amygdala
What pathway is used when responding to acute (immediate) stress
SAM pathway
What is the SAM pathway
Stress - amygdala sends distress signal to hypothalamus - SAM pathway activated - SNS stimulates adrenal medulla - nor/adrenaline secreted into bloodstream - bodily changes for fight or flight
What pathway is used when responding to long term stress
PAS pathway
What is the PAS pathway
Hypothalamus - pituitary gland releases ACTH - adrenal cortex detects ACTH and releases corticosteroids - increased blood sugar available for energy
What is the role of adrenaline in fight or flight
Boost O2 and glucose supply to respond to stressor quickly as well as stopping non emergency bodily processes, e.g digestion
