Show Answers:

  1. What 2 hormones does the adrenal medulla praduse (Catecholamines)
    • 1 Epinephrine (adrenaline)
    • 2 Norepinephrine (noradrenaline; also released by some sympathetic neurons)
  2. what is the main function of testosterone ?
  3. What is the main function of parathyroid hormone (PTH) ?
    It inreases blood calcium concentration by increasing the brakedown of bone with the release of calcium in to the blood.
  4. What is the main function of cacitonin ?
    To decrease the blood calcium concentration by causing calcium to be deposited in the bones.
  5. What is the main function of thyroxine triiodothyronine.
    To increases the rate at which energy is released from carbohydrates.

    It also increases the rate of protein synthesis.

    and lastly accelerates growth and stimulates activity inthe nervous system.
  6. What is the main function of oxytocin (OT) ?
    Stimulates the pregnant uterus to contract.

    may initiate labor.

    Causes glanduler cells of the breast to release milk into ducts.
  7. What is the Main function of Antidiuretic hormone (ADH) ?
    To accelerate water reabsorption from urine in the kidney tubules into the blood there by decreasing urine secretion.
  8. What is the main function of prolactin (PRL) ?
    To stimulate milk production after birth.
  9. What is the main function of growth hormone (GH) ?
    To stimulate an increase in the size and rate of reproduction of the body cells.

    also enhances the movement of amino acids through membranes.
  10. What is the main function of Melanocyte stimulating hormone (MSH)?
    It causes rapid increase inthe synthesis and spread of melanin (pigment in the skin.
  11. what is the function of Luteinizing hormone (LH)?
    It ac with FSH to stimulate estrogen secretion and follicle growth to maturity.

    it causes ovulation.

    it also causes luteinization of the ruptured follicle and stimulates progesterone secretion by corpus luteum.

    lastly it causes interstitial cells in the testes to secret testosterone in males.
  12. what is the main function of the Follicle -stimulating hormone (FSH) ?
    It initiates growth of the ovarian follicles each month in the ovary and stimulates one of more follicles to develop to the stage of maturity and ovulation.

    It also stimulates estrogen secretion by developing follicles.    

    stimulates sperm production in males.
  13. what is the main function of Adrenocorticotopic hormone (ACTH) ?
    To stimulate growth of the adrenal cortex.

    also stimulates the adrenal cortex to secret glucocorticoids (mainly cortisol).
  14. what is the  main function in thyroid stimulating hormone (TSH) ?
    To control the secretion of hormones from the thyroid gland.

    It also stimulates growth of the thyroid gland.

    and stimulates the thyroid gland to secrete thyroid hormone.
  15. what is the main function of melatonin?
    "sleep trigger" role in establishing day night cycle.
  16. what is the main function of insulin ?
    It decreases blood glucose level by promoting movement of glucose out of blood and into cells increasing glucose metabolism by cells.
  17. what is the main function of glucagon?
    Increases blood glucose level by promoting liver glycogenolysis (conversion of glycogen to glucose)
  18. what is the main function of Epinephrine and Norepinephrine ?
    Helps the body resist stress by intensifying and prolonging effects of the sympathetic stimulation.

    Epinephrine secretion is the body's first endocrine response to stress.
  19. What sex hormones are secreted from the Adrenal Cortex ?
    snall amounts of male hormone (androgen) and female hormone (estrogen)
  20. What is the main function of Mineralocorticoids (MCs) ?
    To increase blood sodium and decrease body potassium concentration this is done by accelerating kidney tubule re-absorption of sodium and excretion of potassium.
  21. what are other functions of of glucocorticoids ?
    It acts with epinephrine and norepineprine to produce an anti- inflammatory effect, to bring about normal recovery from inflammation of various kinds. 

    it also produces anti-immunity and antiallergy effects.

    the secretion of glucocorticoid quickly increases when the body is stress.
  22. What is the main functions of Glucocorticoids?
    • To help maintain normal blood glucose concentration by increasing gluconeogenesis.
    • This plays an essential part i maintaining normal blood pressure.
  23. In the ovaries what 3 hormone dose the Placenta produce ?
    • 1 chorionic gonadotropin
    • 2 Estrogen
    • 3 Progesterone
  24. In the ovaries what hormone dose the Thymus produce ?
    1 Thymosin
  25. In the ovaries what hormone dose the corpus luteum produce ?
    1 Progesterone
  26. In the Ovaries what hormone dose the ovarian follicles produce ?
    1 Estrogens
  27. In the Gonads what hormone does the interstitial cells of testes produce ?
    1 Testosterone
  28. What hormone dose the Parathyroid gland produce ?
    1 parathyroid hormone (PTH)
  29. What 2 hormones doe the Thyroid gland produce ?
    • 1 Thyroxine, Triiodothyronine 
    • 2 Calcitonin
  30. what 2 hormones does the posterior pituitary gland produce ?
    • 1 Antidiuretic hormone (ADH)
    • 2 Oxytocin (OT)
  31. what 7 hormones does the anterior pituitary gland produce ?
    • 1 Thyroid stimulating hormone (TSH)
    • 2 Adrenocorticotropic hormone (ACTH)
    • 3 Follicle-stimulating hormone (FSH)
    • 4 Luteinizing hormone (LH)
    • 5 Melanocyte stimulating hormone (MSH)
    • 6 Growth hormone (GH)
    • 7 Prolactin (PRL)
  32. What hormone does the Pineal gland produce ?
    1 melatonin
  33. what 2 hormone dose the pancreatic islets (of Langerhans) produce?
    they do not produce hormones the Alpha and Beta cells in the pancreatic islets praduce the hormones

    • Alpha cells (Glucagon)
    • Beta cells (Insulin)
  34. What are the 3 hormones the adrenal cortex praduses (corticosteriods)?
    • 1 Glucocorticoids
    • 2 Mineralocorticoids (MCs) e.g ,aldosterone
    • 3 Sex Hormones
  35. Name the 9 organs in the endocrine system
