Hormone Table

QuestionAnswer
Human Growth Hormone (hGh) Other name, Secreted from, & Function Somatotroph; Anterior Pituitary; Stimulates tissues to make & release IGF's that promote growth & protein synthesis
Thyroid Stimulating Hormone (TSH) Thyrotrophs; Anterior Pituitary; Stimulates formation & release of thyroid hormones from thyroid gland.
Follicle stimulating hormone (FSH) Gonadotroph; Anterior Pituitary; Females- stimulates development of oocytes, secretion of estrogens; males-stimulates sperm production.
Luteinizing hormone (LH) Gonadotroph; Anterior Pituitary; Stimulates secretion of estrogens & progesterone, ovulation, formation of corpus luteum; males- stimulates testes to produce testosterone.
Prolaction (PRL) Lactotroph; Anterior Pituitary; Promotes milk production
Corticotropin (ACTH)Adrenocorticotropic Hormone Corticotrophs; Anterior Pituitary; Stimulates release of glucocorticoids like cytosol by the adrenal cortex.
Melanocyte stimulating hormone (MSH) Corticotrophs (left over from the pars intermedia); Unknown in human, may effect brain; excess can cause darkening of skin
Oxytocin (OT) Petocin Post Pituitary; Stimulates contraction of uterus during childbirth & milk ejection.
Antidiuretic hormone or vasopressin (ADH) Post Pituitary; Conserves body water by decreasing urine volume, decreases water loss through perspiration, raises blood pressure by constricting arterioles.
T3 ( Triiodothyronine) Follicle; Thyroid; Increases BMR, lipolysis, glucose catabolism, protein anabolism
T4 (Thyroxine) Tetraiodothyronine; Thyroid; Increases BMR, lipolysis, glucose catabolism, protein anabolism.
Calcitonin (CT) Parafollicular; Thyroid; Lowers blood calcium and phosphate by inhibiting bone resorption by ostreoclasts.
Parathyroid (PTH) Chief Cells; Parathyroid; Increases blood calcium & Mg levels & decrease blood phosphate level.
Mineralocorticoids (Aldosterone) Zona Glomerulosa; Adrenal Cortex; Increases levels of Na+ and water, decrease blood levels of K+.
Glucocorticoids (cortisol) Zona Fasciculata; Adrenal Cortex; Increase the catabolism, stimulate lipolysis & gluconeogenesis, provide resistance to stress and reduce inflammation.
Androgens (dehydroepiandosterone) DHEA Zona Reticularis; Adrenal Cortex; Stimulate early growth of axillary and pubic hair in both sexes; females- contribute to libido and are a source of estrogens after menopause.
Epinephrine (adrenaline) EPI Adrenal Medulla; Increase metabolic rate, heart rate. blood pressure, "fight or flight" response.
Norepinephrine (NE) Adrenal Medulla; Stimulates lipolysis, increased heart rate, raise blood pressure.
Glucagon Alpha; Pancreas; Raises blood glucose by stimulating glycogenolysis & gluconeogenesis.
Insulin Beta; Pancreas; Lowers blood glucose by stimulating transport of glucose into cells, glycogenesis, decreasing glycogenolysis & gluconeogenesis, increasing lipogenesis and protein synthesis.
Somatostatin Delta; Pancreas; Inhibits secretion of both insulin & glucagon, slows absorption of nutrients from the GI Tract.
Pancreatic polypeptide F cells; Pancreas; Inhibits secretion of somatostatin, gallbladder contraction, and secretion of pancreatic digestive enzymes.
Estrogens Ovaries;Regulation of female reproductive cycle and process of reproduction.
Progesterone Regulation of female reproductive cycle and process of reproduction.
Relaxin Ovaries; Increases flexibility of pubic symphasis during pregnancy & dialation of cervix during labor & delivery.
Inhibin Ovaries & Testes; Inhibits secretion of FSH.
Testosterone Testes; Stimulates descent of testes before birth, regulates sperm production, responsible for male secondary sex characteristics.
Thymosin,Thymic factor Thymus; Promotes maturation of T cells.
Gastrin GI Tract; Promotes secretion of gastric juice & increases movements of stomach.
Secretin GI Tract; Stimulates secretion of gastric juice & bile.
Choleocystokinin (CKK) GI Tract; Stimulates secretion of pancreatic juice, regulates release of bile from gallbladder, & brings about feelings of fullness after eating.
Human chorionic gonadotropin (hCG) Placenta; Stimulates the corpus luteum in the ovary to continue production of estrogens & progesterone to maintain pregnancy.
Erythropoietin (EPO) Kidneys; Increases rate of RBC formation.
Calcitriol Synthesized in Skin; Kidneys; Aids in absorption of dietary calcium & phosphorus; increases blood calcium
Atrial natriuretic peptide (ANP) Heart; Decreases blood pressure
Leptin Adipose; Suppresses appetite & may increase activity of FSH & LH

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.
