PSC 101 Lecture Notes - Lecture 15: Mental Disorder, Prolactin, Dementia
Document Summary
If you stand to close to lava for too long, it will disrupt homeostasis (lava from. Homeostasis = the stability of internal systems. Stressor = the thing responsible for the imbalance. Stress-response = the body"s response to the imbalance. Lecture 15 - 11/22 - neuroendocrinology of stress. Potential threats to homeostasis: volcano = 700 degrees c, body temperature = 37 degrees c) When you experience a stressor, hormones released from the hypothalamus trigger a cascade of hormonal responses. Hypothalamic response = the paraventricular nucleus (pvn) of the hypothalamus releases corticotropin releasing hormone (crh/crf) (pvn release crh) vessel. Pituitary response = crh stimulates the release of adrenocorticotropic hormone (acth) into general circulation for your entire body. Adrenal response = adrenal cortex releases glucocorticoids; adrenal glands on top of kidneys glucocorticoid receptor (gr) (**estradiol is a subset of the group estrogen; same thing! Cortisol is a subset of the group glucocorticoids)
