Stack #64742 Chapter 18 hormones
hormone | secretion site | action | target cells |
---|---|---|---|
human growth hormone (somatotropin) hGH | Anterior pituitary | promote frowth of body cells, protein synthesis, tissue repair, elevation of blood glucose concentration | liver, muscle, cartilage, bone, other tissues |
Thyroid-stimulating hormone (thyrotropin) TSH | Anterior pituitary | secretion of thyroid hormones (makes and secretes) | thyroid gland |
Follicle-stimulating hormone FSH | Anterior pituitary | females: development of oocytes (eggs), induces ovarian secretion of estrogen; males: stimulates testes to produce sperm | ovaries, testes |
Luteinizing hormone LH | Anterior pituitary | females: secretion of estrogen and progesterone,OVULATION, formation of corpus luteum; males: stimulates testes to develop and produce testosterone | ovaries, testes |
Prolactin PRL | Anterior pituitary | promotes milk secretion by the mammary glands | mammary glands |
Adrenocorticotropic Hormone (corticotropin) ACTH | Anterior pituitary | stimulates secretions of glucocorticoids (mainly cortisol) (stress relief)by adrenal cortex | adrenal cortex |
Melanocyte-stimulating hormone MSH | Anterior pituitary | influence brain activity. Excess causes darkening of the skin | brain, skin |
Oxytocin OT | stored in Posterior Pituitary, made in hypothalamus | contraction of smooth muscles of uterus during childbirth, contraction of mammary glands to cause milk ejection | uterus, mammary glands |
Antidiuretic hormone (vasopressin) ADH | stored in Posterior Pituitary, made in hypothalamus | conserves water, decreases water loss thru perspiration, RAISES BLOOD PRESSURE | kidneys, sudorifoerous glands, arterioles |
T3 tridothyronine | thyroid | increases basal metabolic rate, synthesize proteins, increases glucose and fatty acids for ATP, increases lypolysis, enhances cholesterol excretion, accelerate body growth, help develop nervous system | cells throughout body |
T4 thyroxin | thyroid | increases basal metabolic rate, synthesize proteins, increases glucose and fatty acids for ATP, increases lypolysis, enhances cholesterol excretion, accelerate body growth, help develop nervous system | cells throughout body |
Calcitonin CT | thyroid | BUILDS BONES lowers blood calcium levels, inhibits bone re-absorption by osteoclasts. Uptake of calcium and phosphates into bone matrix | osteoclasts |
Parathyroid PTH | Parathyroid Chief Cells | increases blood calcim and magnesium levels, decreases blood phosphate levels, INCREASES BONE RE-ABSOPTION BY OSTEOCLASTS (BREAKS DOWN BONE) increases calcium re-absorption and phosphate excretion by kidneys, promotes formation of vitamin D, increases rar | kidneys, bones |
mineralocorticoids (aldosterone) | Adrenal Cortex | increase blood levels of sodium and water and decrease blood level of potassium | tubules of kidneys |
Glucocorticoids (cortisol) | Adrenal Cortex | increase protein breakdown (except liver), stimulate gluconogenesis and lipolysis, provides resistance to stress, dampen inflammation, depress immune responses | cells throughout body |
Androgens (dehydroepiandrosterone) DHEA | Adrenal Cortex | early growth of axillary's and pubic hair female: libido, source of extrogen after menopause | reproductive organs |
Epinephrine & Norepinephrine | Adrenal Medulla | produce effect that enhance those of the sympathetice division of the ANS during stress | heart, skeletal muscle, liver, adipose tissue, lungs |
Glucagon | pancreatic isles (alpha cells in pancreas) | increase blood glucose levels by accelarating breakdown of glycogen into glucose in liver, converting other nutrients into glucose in liver, releasing glucose into the blood | liver |
Insulin | Pancreatic isles (beta cells in pancreas) | decrease blood glucose levels, converts glucose into glycogen, decreases glycogenolysis and glycocogenesis, increase lipogenesis and stimulates protein sysnthesis | cells throughout body |
Estrogen and Progesterone | ovarian hormones | regulate female reproductive cycle, regulates oogenesis, maintains pregnancy, prepare mammary glands for lactration, promote development and maintenance of secondary sex characteristics | reproductive organs |
Relaxin | ovaries & placenta | increases flexibility of pubic symphysis during pregnancy, dilate uterine cervix during labor labor and delivery | uterus, pubic symphysis |
Inhibin | ovaries, testes | inhibits secretion of FSH from anterior pituitary | anterior pituitary |
Testosterone | testes | decent of testes before birth, regulates spermatogenesis, promotes development and maintanence of masculine secondary sex characteristics | reproductive organs |
