21721998prolactin (PRL)stimulate and maintains milk production after childbirth
21721999adrenocorticotropic hormone (ACTH)regulates activity of adrenal cortex
21722000thyroid stimulating hormone (TSH)influences growth and activity of thyroid gland
21722001gonadotropic hormoneregulates hormonal activity of gonads
21722002follicle stimulating hormone (FSH) in femalesstimulated development of follicles in ovaries; mature follicles produce estrogen
21722003follicle stimulating hormone (FSH) in malesstimulates sperm development
21722004lutenizing hormone (LH)triggers ovulation; causes ruptured follicle to produce progesterone and estrogen
21722005interstitial cell stimulating hormone (ICSH)stimulates testosterone production
21722006hormones of posterior pituitaryoxytocin, ADH
21722007oxytocinstimulates contractions of uterus, milk ejections, labor; stops postpartum bleeding
21722008antidiuretic hormone (ADH)inhibits urine production; causes kidneys to reabsorb water; increases blood pressure
21722009thyroid gland locationin throat below Adam's apple
21722010thyroid hormonecontrols rate glucose is burned; converts to body heat and chem energy; impt for growth and dev of reproductive and NS
21722011calcitonindecreases blood calcium levels
21722012hormones of thyroid glandthyroid hormone, calcitonin
21722013parathyroid gland locationon thyroid gland
21722014parathyroid hormone (PTH)increases blood calcium levels; stimulates kidneys & intestines to absorb more calcium; breaks down bones
21722015Adrenal Gland locationon top of kidneys
21722016hormones of adrenal cortexmineralcorticoids, glucocorticoids, sex hormones
21722017mineralcorticoidsregulates mineral levels in blood; kidney is target organ; stimulated by humoral factors
21722018atrial natriuretic peptide (ANP)prevents aldosterone release
21722019glucocorticoidshelps body resist long-term stressors; increases blood glucose levels; controls effects of inflammation from edema
21722020sex hormonesproduced in small amounts; males=androgens; females=estrogen
21722021hormones of adrenal medullacatecholamines (epinephrine and norepinephrine)
21722022catecholamines (epinephrine and norepinephrine)stimulates by sympathetic NS; increases heart rate, blood pressure, blood glucose levels and dilates lung passageways
21722023pancreatic islets locationpancreas
21722024hormones of pancreatic isletsinsulin, glucagon
21722025insulinreleased by beta cells when hi levels of blood glucose; takes glucose out of blood to be used by cells
21722026glucagonreleased by alpha cells when low levels of blood glucose; stimulates break down of glyogen to glucose to be released in blood
21722027hormones of pineal glandmelatonin
21722028melatonin"sleep trigger"; established day-night cycle; regulates mating in animals; coordinates hormone fertility in humans; prevents maturing of reprod. sys. before adult body size

21723502ovaries locationfemale pelvis
21723503hormones of ovariesestrogen, progesterone
21723504estrogenstimulates development of secondary characteristics in females; prepares uterus for fertilization; menstrual cycle; maintains pregnancy and milk production
21723505progesteronemenstrual cycle; quiets uterus muscles during pregnancy; prepares for lactation
21723506corpus luteumproduces and secretes mainly progesterone (and some estrogen)
21723507testes locationin the scrotum
21723508hormones of the testesandrogens (i.e. testosterone)
21723509testosteronestimulated by LH; causes development of male sex characteristics; stimulates male sex drive
