Physio endocrine

brief Hormones for physio test 1

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
