Fight or Flight - BIOPSYCHOLOGY Flashcards
what is fight or flight
the body’s response to stress
which brain region processes fear/pain
the amygdala
which brain region controls homeostasis
the hypothalamus
what is the pituitary gland
‘master gland’ - controls other glands
what is ACTH
(adrenal gland) - starts production of adrenaline and noradrenaline
what is CRH
(adrenal gland) - starts production of cortisol
what does the adrenal medulla process
adrenaline and noradrenaline
what does the adrenal cortex produce
cortisol
what is acute stress
short-term and intense stress. adaptive and healthy
what is chronic stress
long-term and exhausting stress. maladaptive (not good for survival) and unhealthy
what does the HPA axis stand for
hypothalamus, pituitary gland, and adrenal glands
what is HPA dysfunction
unnecessary stress response maintained
….brain receives “false” danger/perceived threat signal which overpowers the endocrine stress feedback signal which was meant to happen
where does the ‘stressor’ signal immediately go to
the amygdala
which two places will this stressor signal go to from the amygdala
either the pituitary gland or the hypothalamus
when does the amygdala send the stressor signal to the pituitary gland
brain ‘danger’ signal (perceived threat) - is the more powerful signal
