an overactive immune system
The GAS three stages are:
1. the alarm stage
2. adaption or stage of resistance
3. stage of exhaustion
diseases of adaption develop if the sage of resistance or adaption does not restore homeostasis.
How does the neuroendocrine system respond to stress:
uses sympathetic stimulation of the adrenal medulla to secreate epinephrine and norepinephrine and stressor induced stimulation of the pituitary to secrete ACTH which in turn stimulates the adrenal cotex to secrete steroid hormones particularly cortisol
What is the purpose of Catecholamines?
they prepare the body to act and cortisol mobilizes energy (glucose) and other substances needed to fuel the action.
