  1. releasing and inhibiting factors
    (gland, target, effect)
    • gland: hypothalamus
    • target: anterior pituitary
    • effect: modify activity
  2. growth hormone
    (gland, target, effect)
    gland: anterior pituitary

    effect: increase bone/muscle growth, increase cell turnover rate
  3. prolactin
    (gland, target, effect)
    • gland: anterior pituitary
    • target: mammary gland
    • effect: milk production
  4. thyroid stimulating hormone
    (gland, target, effect)
    • gland: anterior pituitary (tropic)
    • target: thyroid
    • effect: increase synthesis and release of thyroid hormone
  5. adrenocorticotropic hormone (ACTH)
    • gland: anterior pituitary
    • target/effect: increase growth an dsecretory activity of adrenal cortex
  6. lutenizing hormone
    • gland: anterior pituitary (gonadotropic)
    • target: ovary/testes
    • effect: ovulation/testosterone growth
  7. follicle stimulating hormone
    • gland: anterior pituitary (gonadotropic)
    • target: ovary/testes
    • effect: follicle development/spermatogenesis
  8. adtidiuretic hormone (ADH aka vasopressin)
    • gland: posterior pituitary
    • target: kidney
    • effect: water retention
  9. oxytocin
    • gland: posterior pituitary
    • target: breast/uterus
    • effect: milk letdown/contractions during birth
  10. calcitonin
    • gland: thyroid C cells
    • target: bone, kidney
    • effect: lowers serum (Ca2+)
  11. parathyroid hormone (PTH)
    • gland: parathyroids
    • target: bone, kidney, small intestine
    • effect: raises serum (Ca2+)
  12. thymosin
    • gland: thymus
    • target:/effect: T cell development during childhood
  13. insulin
    • gland: endocrine pancrease (secreted by beta cells)
    • target: blood
    • effect: lowers blood glucose, increases glycogen and fat storage
  14. glucagon
    • gland: endocrine pancreas (secreted by alpha cells)
    • target: blood
    • effect: raises blood glucose, decrease glycogen and fat storage
  15. somatostatin
    • gland: secreted by gamma cells
    • target/effect: inhibits many digestive processes
  16. atrial natriuretic factor (ANF)
    • gland: heart
    • target: kidney
    • effect: increase urination to lower blood pressure
  17. erythropoietin
    • gland: kidney
    • target: bone marrow
    • effect: increase RBC synthesis
  18. cortisol (aka glucocorticoid)
    • gland: adrenal cortex
    • target/effect:
    • - longer term stress response
    • - increase blood glucose
    • - increase protein catabolism
    • - decrease inflammation and immunity
  19. aldosterone
    • gland: adrenal cortex
    • target: kidney
    • effect: increase Na+ readsorption to increase blood pressure
  20. sex steroids
    • gland: adrenal cortex
    • target/effect: an adrenal tumor can overproduce these, causing masculinization or feminization.
  21. testosterone
    • gland: testes
    • target/effect: male characteristics, spermatogenesis
  22. estrogen
    • gland: ovaries/placenta

    • target/effect: endometrial secretion and pregnancy
  24. thyroid hormone
    • gland: thyroid
    • target/effect:
    • - children: physical and mental development
    • - adults: increase metabolic rate and temperature
  25. epinephrine
    • gland: adrenal medulla
    • target/effect: rapid sympathetic stress response
