Document Summary
List all functions of hypothalamic neurohormones oxytocin and adh. Oxytocin: strong stimulant of uterine contraction, released during childbirth, triggers milk production, surges during sexual arousal/orgasm, functions in emotional bonding (sexual/maternal) Antidiuretic: inhibits/prevents urine formation, regulates water balance, targets kidney tubules to transorb more water. List all the stimuli that trigger adh release; homeostatic imbalance. Its release is triggered by: high concentration of solutes in blood, pain, low blood pressure, drugs such as nicotine, morphine, barbiturates. Release also triggered by pain, low blood pressure, and drugs. List names (extended and abbreviated) and functions of all releasing and inhibitory factors produced by the hypothalamus; trh, crh, gnrh, ghrh, ghih, pih. Trh, (thyrotropin releasing hormone) promotes secretion of thyroid stimulating hormone and prolactin. Crh, (corticotropin releasing hormone) promotes secretion of adrenocorticotropic hormone. Gnrh, (gonadotropin releasing hormone) promotes secretion of follicle stimulating hormone and luteinizing hormone. Ghrh, (growth hormone releasing hormone) promotes secretion of growth hormone.
