Antidiurectic hormone (ADH) |
gland : Posterior Pituitary Function: Increases water absorption from from kidneys Raises blood pressure regulated by : hypothalamus secretions, blood osmolarity |
|
Oxytocin gland: , Action: 2, hormone regulator:3 |
-Posterior Pituitary -contraction of pregnant uterus -release of breastmilk -hypothalamus secretions, uterine stretch, suckling infant |
|
Somatotropin (growth hormone) |
-Anterior pituitary gland -bone and muscle growth -promotes protein synthesis and fat mobilization -hypothalamus secretions |
|
Prolactin |
-Anterior Pituitary gland -production of milk after childbirth -hypothalamic hormones |
|
Thyroid-stimulating hormone (TSH) |
-Anterior pituitary gland -stimulates production and secretion of thyroid hormones -Blood thyroxine levels & hypothalamic secretions |
|
Adrenocorticotropic hormone (ACTH) |
-Anterior Pituitary Gland -stimulates adrenal cortex to secrete cortisol and other steroids -(CRH) Corticotropin-releasing hormone from Hypothalamus & blood cortisol levels |
|
LH Luteinizing hormone (LH) FEMALE (ICSH) Interstitial cell stimulating hormone MALE |
Anterior pituitary Gland Initiates ovulation in females and secretion of sex hormones in both male and female -hypothalamic secretions -estrogen and testosterone levels |
|
FSH Follicle stimulating hormone |
-Anterior Pituitary Gland -Stimulates development of ovum in females -development of sperm in testes in males -hypothalamic secretions -progesterone |
|
Tetraiodothryonine (thryoxine T4) triiodothyronine (T3) |
Thyroid gland -increases oxygen consumption -increases heat production -maintains metabolic processes -TSH regulated by TRH from hypothalamus |
|
Calcitonin |
-Thyroid Gland -Inhibits calcium release from bone , which lowers blood calcium levels -regulated by blood calcium concentrations |
|
Parathyroid hormone (PTH) |
-Parathyroids -increases blood calcium by stimulating calcium release from bone; which decreases blood phosphate level -regulated by calcium concentrations in blood |
|
thymosin and thymopoietin hormones; thymic humoral factor ; thymostimulin , factor thymic serum |
-Thymus gland -stimulate T cell development and maturation in Thymus -maintenance of other lymph tissue -B cells develop to plasma cells -not known what regulated by |
|
Melatonin |
-Pineal gland -circadian rhythms -antigonadotropic effect induces sleep exposure to light/dark cycles darkness stimulates release light diminishes release |
|
Epinephrine |
-Adrenal Medulla -constricts blood vessels in skin, kidneys and gut to increase blood supply to heart, brain and skeletal muscles -increase HR increase BP Increase Blood Glucose levels -stimulation of smooth muscle contraction (tightens so contents propel, ) -innervated by Sympathetic nervous system |
|
Norepinephrine |
-Adrenal Medulla -blood vessel constriction -increase HR -increase metabolic rate -contraction of cardiac muscles -Sympathetic nervous system |
|
Glucocorticoids (a corticosteroid) |
-Adrenal Cortex -regulates blood glucose by carb metabolism -affects growth -decrease effects of stress and anti-inflammatory agents -metabolize protein and fats -ACTH -Stress -serum electrolyte concentrations |
|
Mineralcorticoids (mainly Aldosterone) (a corticosteroid) |
-Adrenal Cortex -regulate sodium , water and potassium excretion by kidneys -regulated by Renin and angiotensin |
|
Gonadocorticoids (mainly Androgen) (a corticosteroid) |
-Adrenal cortex -contributes to secondary sex characteristics (women have a larger androgeneric effect after menopause) -ACTH |
|
Insulin |
-Pancreas 's Islets of Langerhans cells -lowers blood sugar -increases carb storage as glycogen storage in liver -decreases gluconeogenesis -Blood glucose concentrations |
|
Glucagon |
Pancreas's Islets of Langerhans cells -raises blood sugar -stimulates glycogen breakdown in liver (glycogenolysis) -Blood glucose -amino acid concentration |
|
Estrogen |
-Ovarian follicle -develop and maintain female sex organs and characteristics -initiate building of uterine lining and maintenence of pregnancy -FSH and LH |
|
Androgens (mainly testosterone) |
Testes gland -develop and maintain male sex organs -develop male sex characteristics -aid sperm production -FSH & ICSH |
|
Progesterone and Estrogens |
-Ovary (corpus luteum) -influences breast development mammary glands and ducts -menstrual cycles -growth and differentiation of uterine lining -maintain pregnancy -FSH |
|
Instrinsic Factor |
-principal site of action Small Intestine -needed for the absorption of B12 |
|
Cholecystokinin |
GI Tract -principal site of action Gallbladder -main action contraction and emptying |
|
Pancreozymin |
GI tract -principal site of action pacreas -production of pacreatic juice rich in enyzymes |
|
Gastrin |
GI tract acts on stomach to produce gastric juice |
|
Enterogastrone |
GI tract acts on stomach to inhibit secretion and motility |
