  1. Adrenocorticotropic hormone (ACTH)
    stimulates cortisol production and release from adrenal gland
  2. Luteinizing hormone (LH)
    stimulates production of testosterone in testes and estrogen in ovaries
  3. follicle-stimulating hormone (FSH)
    stimulates production of estradiol and eggs (W) and sperm (M)
  4. Melanocyte-stimulating hormone (MSH)
    stimulates production and release of melanin by melanocytes in skin and hair
  5. thyroid stimulating hormone (TSH)
    controls thyroid hormone formation and release from thyroid gland
  6. Prolactin
    directly stimulates breast to produce milk
  7. Growth Hormone (GH)
    stimulates release of insulin-like growth factors (IGFs) from liver and other tissues
  8. where is IGF also produced and what is it associated with
    it is also produced in muscle (d/t muscle contraction) and is associated with muscle hypertrophy
  9. Why is GH essential for growth of all tissues?
    it stimulates AA uptake by tissues and protein synthesis and it is used in long bone growth
  10. How doe the GH spare plasma glucose?
    • it decreases use of plasma glucose by opposing insulin action¬†
    • - increases gluconeogenesis in liver
    • -mobilizes fatty acids from adipose tissue by using FA for energy right away
  11. what are some childhood growth hormone disorders?
    • -gigantism- excess GH
    • -Dwarfism- inadequate secretion (treated with gh)
  12. what are some GH disorders in adulthood?
    • -acromegaly- too musch GH (permanent deformities)
    • - thickened bones in face, hands, and feet
  13. oxytocin
    • powerful smooth muscle stimulator (uterine contraction)
    • - let down response to release milk from breast
  14. Antidiuretic hormone (ADH)
    • -lowers water loss from body to maintain plasma volume¬†
    • -
