Stack #64742 hormone

Stack #64742 Chapter 18 hormones

hormonesecretion siteactiontarget 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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
