Physio Hormones
Question | Answer |
---|---|
action of TRH | stimulates secretion of TSH and prolactin |
action of CRH (corticotropin-releasing hormone) | stimulates secretion of ACTH |
action of GnRH | stimulates secretion of LH and FSH |
action of SRIF | inhibits secretion of growth hormone |
action of GHRH | stimulates secretion of GH |
action of PIF | inhibits secretion of prolactin |
action of TSH | stimulates secretion of thyroid hormones |
action of FSH | stimulates sperm maturation in sertoli cells stimulates ovulation, formation of corpus luteum, estrogen and progesterone synthesis |
action of growth hormone | stimulates protein synthesis and overall growth |
action of prolactin | stimulates milk production and secretion |
action of ACTH (adrenocorticotropic hormone) | stimulates synthesis and secretion of adrenal cortical hormones (cortisol, aldosterone, etc) |
action of MSH (melanocyte-stimulating hormone) | stimulates melanin synthesis |
action of oxytocin | stimulates milk ejection and uterine contractions |
action of ADH/vasopressin | stimulates water re-absorption in the collecting ducts |
action of T3/T4 | stimulates overall basal metabolic rate - heat production, oxygen consumption, fat, protein & CHO utilization |
action of calcitonin | decreases serum [Ca] |
action of parathyroid hormone | increases serum [Ca] |
action of Cortisol | stimulates gluconeogenesis, inhibits inflammatory response, suppresses immune system |
action of aldosterone | increases renal Na re-absorption and K secretion |
action of DHEA and androstenedione | see action of testosterone |
action of testosterone | stimulates speratogenesis, stimulates secondary sex characteristics |
action of estradiol | stimulates growth and development of female reproductive system, follicular phase of menstrual cycle, development of breasts, prolactin secretion, maintains pregnancy |
action of progesterone | stimulates luteal phase of menstrual cycle; maintains pregnancy |
action of HCG (human chorionic gonadotropin) | stimulates estrogen and progesterone synthesis in corpus luteum of early pregnancy |
action of HPL (human placental lactogen) | has growth hormone like and prolactin like actions during pregnancy |
action of insulin | decreases blood [glucose] |
action of glucagon | increases blood [glucose] |
action of renin | catalyzes conversion of angiotensinogen to angiotensin I |
action of 1,25 dihydroxycholecalciferol | increase intestinal absorption of Ca; bone mineralization |
Hormone of the posterior pituitary | Vasopressin/ADH and oxytocin |
