What is stress? (as defined by Dr.Hoey) | Response to a stressor |
What is a stressor? | Anything that disrupts physiological homeostasis and causes a stress response. |
Are all stressors bad? | No. |
Which 2 endocrine systems constitute the major components of the stress response? | Epinephrine (from adrenal medulla) & glucocorticoids (from adrenal cortex) |
What is a stress response? | Physiological and behavioral changes that help reestablish homeostasis |
Name the 3 phases in the general adaptation syndrome. | Alarm, resistance & exhaustion |
When is a stress response adaptive; long term or in short term stress? | Short term stress |
Recall the HPA axis diagram. | |
The HPA axis is activated so that ________, __________, and __________ are released in response to stressors. | CRH, ACTH, and glucocorticoids |
List the 3 reasons why glucocorticoids are good candidates for mediating behavioral effects of stress. | 1) these steroid hormones are released in response to numerous stressors 2) steroid hormones can easily diffuse past the blood-brain barrier 3) glucocorticoid receptors are present in several brain regions |
