physiology of the stress response
are processed in the CORTICOLIMBIC SYSTEM
when threat, message sent to PNS for prepare for movement
Message also sent to hypothalamus which controls the autonomic nervous system, and the sympathetic nervous system is activated
hypothalamus communicates with endocrine system to activate the adrenocortical and adrenomedullary system
adenocortical
releases cortisol to increase SNS activity
suppresses immune response, increase release of stored fat
adrenomedullary
releases adrenaline
General Adaptation syndrome
Alarm – SNS activated
Resistance – Body uses hormones to keep system elevated
Exhaustion–resources are depleted, body is exhausted
long-term impact of cortisol
suppresses immune system and can disrupt sleep
more likely to become stick
