    Anterior pituitary
  8. Follicle-stimulating hormone (FSH) class
    Peptide and water-soluble
  9. Follicle-stimulating hormone (FSH) function

    Anterior pituitary
  11. Thyroid-stimulating hormone (TSH) class
    Peptide and water-soluble
  12. Thyroid-stimulating hormone (TSH) function
    Stimulates release of T3/T4 from the thyroid.
  13. Human Growth hormone (hGH) location of synthesis
    Anterior pituitary
  14. Human Growth hormone (hGH) class
    Peptide and water-soluble
  15. Human Growth hormone (hGH) function
    Stimulates growth throughout the body.
  16. Prolactin location of synthesis
    Anterior pituitary
  17. Prolactin class
    Peptide and water-soluble
  18. Prolactin function
    Stimulates milk production in the breasts.
  19. Antidiuretic hormone (ADH) location of synthesis
    Posterior pituitary
  20. Antidiuretic hormone (ADH) class
    Peptide and water-soluble
  21. Antidiuretic hormone (ADH) function
    Causes the collecting duct of the kidney to become highly permeable to water, concentrating the urine.
  22. Oxytocin location of synthesis
    Posterior pituitary
  23. Oxytocin class
    Peptide and water-soluble
  24. Oxytocin function
    Stimulates contractions during childbirth and milk secretion during nursing.
  25. Parathyroid hormone location of synthesis
  26. Parathyroid hormone class
    Peptide and water-soluble
  27. Parathyroid hormone function
    Increases blood calcium by stimulating proliferation of osteoclasts, uptake of Ca2+ in the gut, and reabsorption of Ca2+ in the kidney.
  28. Insulin location of synthesis
  29. Insulin class
    Peptide and water-soluble
  30. Insulin function
    Stimulates uptake and storage of glucose from the blood.
  31. Glucagon location of synthesis
  32. Glucagon class
    Peptide and water-soluble
  33. Glucagon function
    Stimulates gluconeogenisis and release of glucose into the blood.
  34. Calcitonin location of synthesis
  35. Calcitonin class
    Peptide and water-soluble
  36. Calcitonin function
    Decreases blood calcium by inhibiting osteoclasts.
  37. Human chorionic gonadotropin (hCG) location of synthesis
  38. Human chorionic gonadotropin (hCG) class
    Peptide and water-soluble
  39. Human chorionic gonadotropin (hCG) function

    Adrenal cortex
  41. Aldosterone class
    Steroid and lipid-soluble
  42. Aldosterone function
    Increases Na+ reabsorption and K+ secretion at the distal convoluted tubule and the collecting duct; net increase in salts in the plasma, increasing osmotic potential and subsequently blood pressure.
  43. Cortisol location of synthesis
    Adrenal cortex
  44. Cortisol class
    Steroid and lipid-soluble
  45. Cortisol function
    A stress hormone; increases gluconeogenesis in the liver and thus blood glucose levels; stimulates fat breakdown.
