Show Answers:

  1. function of TSH (thyroid-stimulating hormone)
    stimulates synthesis and release of thyroid hormone (TH)
  2. function of ACTH (adrenocorticotropin hormone)
    stimulates synthesis and release of corticosteroids and adrenocortical growth
  3. function of LH (lutenizing hormone)
    • stimulates ovulation and progesterone secretion
    • stimulates testosterone secretion
  4. function of FSH (follicle-stimulating hormone
    • stimulates estogen secretion and follicle maturation
    • stimulates spermatogenesis
  5. function of PRL (prolactin)
    stimulates breast milk production
  6. function of GH (growth hormone)
    promotes growth
  7. function of MSH (melanocyte-stimulating hormone)
    promotes pigmentation
  8. function of ADH (antidiuretic hormone)
    promotes water reabsorption/retention
  9. function of oxytocin
    stimulates uterine contractions and ejection of breast milk
  10. function of T3 and T4
    control the metabolic rate of all cells
  11. function of PTH (parathyroid hormone)
    regulate calcium and phosphorus by acting the kidneys, intestinal tract, and bone

    ** kidney tubules allow Ca to be reabsorbed and put back into the blood
  12. function of glucagon
    increases blood glucose levels; enhances lipolysis

    ** liver & glucogenolysis
  13. function of somatostatin
    • inhibits the release of glucagon and insulin from the pancreas
    • important part of the body's response to stress
  14. function of cortisol
    • antiinflammatory effects
    • affects carbohydrate, protein, and fat metabolism
    • body's response to stress
    • immune function
  15. function of aldosterone
    • maintains ECF volume
    • promotes sodium and water reabsorption and potassium excretion in the kidney tubules
  16. function of epinephrine & norepinephrine
    • body's response to stress
    • flight-or-fight
  17. function of insulin
    • lowers blood glucose levels
    • promotes the movement of carbohydrate, fat, and protein
