oxytosin (OT)

What hormone stimulates UTERINE CONTRACTIONS and MILK EJECTION (let down) during suckling

corticotropin (ACTH)

What hormone STIMULATES secretion of hormones by the ADRENAL CORTEX and stimulates secretion of insulin (by pancreas)

antidiuretic hormone (vasopressin, ADH)

What hormone targets the KIDNEYS and decreases water loss by increasing REABSORPTION of WATER into blood and decreasing urine production. Also increases blood pressure by arteriole contriction

androgen

What hormone INCREASES LIBIDO in WOMEN

T3 (triiodothyronine), T4 (thyroxine, tetraiodothyronine)

What hormone increases metabolism (use of glucose and fatty acids for ATP); synthesis of protein; increase BMR; cholesterol excretion; and development of nervous system (two hormones)

luteinizing hormones (LH)

What hormone triggers ovulation and stimulates secretion of estrogen and progesterone

parathyroid hormone (PTH)

What hormone increases blood calcium levels by stimulating osteoclast activity

epinephrine, norepinephrine (E, NE)

What hormone promotes fight-or-flight response (two hormones) during stress or crisis

prolactin (PRL)

What hormone stimulates production and secretion of milk

cortisol

What hormone increases resistance to stress, increases blood glucose levels, and decreases inflammation and immune response and increases protein breakdown (catabolism)

melatonin

What hormone helps to set the biological clock

melanocyte stimulating hormone (MSH)

What hormone darkens skin pigmentation

hGHRH and TRH

What hormone stimulates secretion of hormones that stimulate body growth and metabolism?

calcitonin

What hormone decreases blood calcium levels by inhibiting osteoclasts

thymosin

What hormone promotes the maturation of T cells for the immune response

follicle stimulating hormone (FSH)

What hormone stimulates oocyte production and estrogen secretion

insulin

What hormone decreases blood glucose levels by transporting glucose into body cells

PTH

What hormone promotes formation of calcitriol, responding to low calcium levels in blood

insulin

What hormone stimulates the formation of fat

glucagon

What hormone increases blood glucose levels by stimulating the liver to break down glycogen into glucose

estrogen and progesterone

What hormone stimulates developent of female sex characteristics and helps regulate menstrual cycle (two hormones)

follicle stimulating hormone (FSH)

What hormone regulates sperm development, stimulates development of male sex characteristics and stimulates male sex drive

luteinizing hormone (LH)

What hormone stimulates secretion of testosterone

thyroid stimulating hormone (thyrotropin, TSH)

What hormone stimulates secretions of thyroid hormones

FSH, testosterone

What hormone(s) stimulates sperm production

aldosterone

What hormone increases reabsorption of sodium (Na) and water into blood and decreases urine output (this in turn increases blood pressure) also decreases potassium K+ levels in blood

calcitriol

What hormone increases calcium and phosphates absorption from gastrointestinal tract into blood

leptin

What hormone supresses appetite and MAY increase FSH and LH secretion

cholecystokinin (CCK)

What hormone aids in digestion (by regulating bile in gallbladder and stimulating pancreatic juices) causes feeling of fullness after eating

gastrin

What hormone aids in digestion (by increasing movement of stomach and gastric juices)

secretin

What hormone aids in digestion (by STIMULATING SECRETION OF pancreatic juice and bile)

GIP, hGH, ACTH, glycagon

What hormones directly STIMULATE release of INSULIN by pancreatic Beta cells

hCG (human chorionic gonadotropin)

What hormone maintains estrogen and progesterone levels during PREGNANCY

thyroid stimulating hormone (thyrotropin, TSH)

What hormone can expand the size of thyroid?

thyroid stimulating hormone (thyrotropin, TSH)

What hormone increases iodide uptake?

somatostatin (GHIH, growth hormone inhibiting hormone)

What hormone inhibits hGH secretion?

somatostatin (GHIH, growth hormone inhibiting hormone)

What hormone inhibits TSH secretion?

dopamine (PIH, prolactin inhibiting hormone)

What hormone inhibits prolactin secretion?

dopamine

What hormone inhibits MSH secretion?

somatocrinin (GHRH, growth hormone releasing hormone)

What hormone stimulates hGH secretion?

thyrotropin releasing hormone (TRH)

What hormone stimulates TSH secretion?

gonadotropin releasing hormone (GnRH)

What hormone stimulates FSH and LH secretion?

prolactin releasing hormone (PRH)

What hormone stimulates prolactin secretion

corticotropin releasing hormone (CRH stimulates corticotropin which is ACTH)

What hormone stimulates what hormone stimulates corticotropin?

corticotropin releasing hormone (CRH)

What hormone stimulates MSH?

erythropoietin (EPO)

What hormone increases the rate of red blood cell formation?

renin

What enzyme raises blood pressure by causing vasoconstriction and secretion of aldosterone?

DHEA (an androgen)

What hormone stimulates early growth of axillary and pubic hair and contributes to female libido estrogens after menopause?

calcitriol

What hormone is the active form of vitamin D?

atrial natriuretic peptide (ANP)

What hormone is produced by the heart to decrease blood pressure?

ADH, aldosterone

What hormones raise blood pressure?

ANP

What hormones lower blood pressure?

insulin, GHIH (somatostatin)

What hormones lower blood glucose in blood? (response to hyperglycemia)

glucagon, GHIH??, pancreatic polypeptide

What hormones raise blood glucose in blood? (response to hypoglycemia)

calcitonin

What hormones lower blood calcium and lowers phosphorus in blood?

PTH, calcitriol

What hormones raise blood calcium but lower phosphorus in blood?

aldosterone (K),
