Can somebody give me a example of homeostatic control?
it is a combination of the “sympathetic adrenomedullary axis” SAM and “hypothalamic pituitary adrenal axis” HPA that provide the stress response system “fight or flight” through a negative feedback loop this is a physiological response to a stimulus in the environ, i.e. upcoming test at school the hypothalamus (which is the control center for homeostasis) responds to the stimulus by producing CRH The key elements of the HPA axis are: The paraventricular nucleus of the hypothalamus, which contains neuroendocrine neurons that synthesize and secrete vasopressin and corticotropin-releasing hormone (CRH). These two peptides regulate: The anterior lobe of the pituitary gland. In particular, CRH and vasopressin stimulate the secretion of adrenocorticotropic hormone (ACTH), once known as corticotropin. ACTH in turn acts on: the adrenal cortices, which produce glucocorticoid hormones (mainly cortisol in humans) in response to stimulation by ACTH. Glucocorticoids in turn act back on the hypothal
