    • in the anterior pituitary
  3. Hypothalamus
    GnRH
    (Gonadotropin-releasing hormone)
    • Promotes secretion of FSH and LH
    • (follicle-stimulating hormone and Luteinizing hormone)
    • in the anterior pituitary
  4. Hypothalamus
    GHRH
    (Growth hormone-releasing hormone)
    • Promotes secretion of GH
    • (growth hormone)
    • in the anterior pituitary
  5. Hypothalamas
    PIH
    (prolactin-inhibiting hormone)
    • Inhibiting secretion of PRL
    • (prolactin)
    • in the anterior pituitary
  6. Hypothalamas
    Somatostatin
    • Inhibiting secretion of GH and TSH
    • (growth hormone and thyroid-stimulating hormone)
    • in the anterior pituitary
  7. Anterior pituitary
    FSH
    (Follicle-stimulating hormone)
    • Female & Male: growth of ovarian folicles (secretion of estrogen), sperm production
    • in the overies, testes
  8. Anterior Pituitary
    LH
    (luteinizing hormone)
    • Female & Male: ovulatin, testosterone secretion
    • in the ovaries and testes
  9. Anterior pituitary
    TSH
    (thyroid-stimulating hormone)
    • Growth of thyroid and secretion of thyroid hormone
    • in the thyroid gland
  10. Anterior pituitary
    GH
    (growth hormone)
    • widespread tissue growht
    • in the liver, bone, cartilage, muscle, fat
  11. Anterior pitutary
    ACTH
    (Adrenocorticotropic hormone)
    • Growth adrenal cortex, secretion of glucocorticoids
    • in the adrenal cortex
  12. Anterior pituitary
    PRL
    (prolactin)
    • female & male: milk secretion, increased LH sensitivity
    • in mammary glands and testes
  13. Posterior pituitary
    ADH (vasopressin)
    (Antidiuretic hormone)
    • Water retention
    • in the kidneys
  14. Posterior Pituitary
    OT
    (oxytocin)
    • Labor contraction, milk release; possible involved in ejaculation, sperm transport, sexual affection, and mother-infant bonding
    • in uterus, mammary glands
  15. Pineal gland
    Melatonin
    • Uncertain; may influence mood and sexual maturation
    • in the brain
  16. Thymus
    the 3 T's
    Thymopoietin, thymosin, thymulin
    • Stimulate T lymphocyte development and activity
    • in the immune cells (T lymphocytes)
  17. Thyroid
    T3, T4
    (thyroxine and triiodothyronine)
    • Elevate metabolic rate and heat production
    • increases RR, HR, and strength of heartbeat
    • stimulates appetite & accelerate breakdown of nutrients
    • promotes alertness and quicken reflexes
    • stimulates GH secretion and growth of skin, hair, nails, teeth, and fetal nervous system
    • in MOST tissues
  18. Thyroid
    Calcitonin
    • stimulates bone depostion, mainly in children
    • in the bones
  19. Parathyroid
    PTH
    (parathyroid hormone)
    • Raises blood Ca2 level by stimulating bone resorption and inhibiting depostion, reducing urinary Ca2 exeretion, and ehancing calcitriol synthesis
    • in the bone, kidenys, small intestine
  20. Adrenal medulla
    epinephrine, NE
    (epinephrine, norepinephrine)
    • Promote alterness
    • mobilize organic fuels
    • raise metabolic rate
    • stimulate circulation and respiration
    • increase blood glucose level
    • inhibit insulin secretion and glucose uptake by insulin-dependent organs (sparing glucose for brain)
    • in MOST tissues
  21. Adrenal Cortex
    aldosterone/mineralcorticoids
    • Promotes Na and water retention and K excretion
    • maintains BP and volume
    • in kidney
  22. Adrenal Cortex
    Corisol/glucocorticoids
    • Stimulate fat and protein catabolism, gluconeogenesis, stress resistance and tissue repair
    • in MOST tissue
  23. Pancreas
    insulin
    • stimulates glucose and amino acide uptake
    • lowers blood glucose level
    • promotes glycoge, fat and protein synthesis
    • in MOST tissues
