brief Hormones for physio test 1
Question | Answer |
---|---|
hormones from hypothalamus | TRH, CRH, GnRH, GHRH, somatostatin, dopamine |
hormones from anterior pituitary | TSH, FSH, LH, ACTH, MSH, growth hormone, prolactin |
hormones from posterior pituitary | oxytocin, ADH |
hormones from thyroid | T3, T4, calcitonin |
hormones from pancreas | insulin, glucagon |
hormones from kidney | renin, 1,25-dihydroxycholecalciferol |
hormones from adrenal cortex | cortisol, aldosterone, adrenal androgens |
function of TRH | stims release of TSH, prolactin |
function of CRH | stims secretion of ACTH |
function of GnRH | stims secretion of LH and FSH |
function of GHRH | stims secretion of growth hormone |
function of somatostatin | inhibits secretion of growth hormone |
function of dopamine | inhibits secretion of prolactin |
function of TSH | stims formation/ secretion of thyroid hormones |
function of FSH | stims sperm maturation in sertoli cells of testes |
function of LH | stims testosterone synthesis in Leydig cells of testes |
function of ACTH | stims synthesis/ secretion of cortisol, androgens, aldosterone |
function of MSH | stims melanin synthesis |
function of growth hormone | stims protein synthesis and overall growth |
function of prolactin | stims milk production/ secretion in breast |
function of oxytocin | stims milk ejection from breast and uterine contraction |
function of ADH | stims water reabsorption in principal cells of collecting ducts, constriction of arterioles |
function of T3, T4 | stims skeletal growth, oxygen consumption, heat production, protein/fat/carb utilization, perinatal maturation of CNS |
function of PTH | increase serum [Ca2+] |
function of insulin | decrease blood [glucose] |
function of of glucagon | increase blood [glucose] |
function of renin | convert angiotensinogen to angiotensin 1 |
function of 1,25-dihydroxycholecalciferol | (activated vitamin D) increase intestinal absorption of Ca2+, bone mineralization |
function of cortisol | stims gluconeogenesis, inhibits inflammatory response, suppresses immune response, enhances vascular responsiveness to catecholemines |
function of aldosterone | increases renal Na+ reabsorption, K+ and H+ secretion |
