5 Matching questions

  1. Renin
  2. Thyroxine
  3. Melatonin
  4. Thyroid Stimulating Hormone
  5. Retinol Binding Protein 4
  1. a causes thyroid gland cells to secrete T3 and T4; stimulates thyroid growth
  2. b enzyme that is produced by the kidney; important for blood pressure and volume regulation; catalyzes the conversion of circulating angiotensinogen to angiotensin I
  3. c hormone produced by the thyroid glands to regulate metabolism by controlling the rate of oxidation in cells
  4. d targets the brain to control circadian rhythms and circannual rhythms, and may be involved in maturation of sex organs
  5. e Function not well understood; secreted by adipocytes (fat cells) and may communicate signal low blood sugar; recently associated with the development of insulin insensitivity

5 Multiple choice questions

  1. signals the release of adrenocorticotropic hormone (ACTH) from the pituitary
  2. In male embryos, turns off the development of a uterus and other female structures.
  3. promotes water retention, in high concentrations is also a vasoconstrictor. both of these effects raise the blood pressure
  4. noradrenaline; chemical which is excitatory, similar to adrenaline, and affects arousal and memory; raises blood pressure by causing blood vessels to become constricted
  5. secreted by gastrointestinal tract; enhance glucose-stimulated release of insulin; inhibit glucagon

5 True/False questions

  1. Angiotensinprohormone produced by the liver then converted by renin to angiotensin I, then that is converted by ACE to angiotensin II which is a vasoconstrictor


  2. Cholecystokinintargets the mammary glands stimulating them to produce breastmilk


  3. Adrenocorticotropic HormoneIncreases blood levels of calcium (stimulates breakdown of bone and rate at which calcium is removed from urine and absorbed from the gastrointestinal tract)


  4. Orexinplays a critical role in preventing abnormal consciousness transitions, particularly into REM sleep; may stimulate hunger


  5. Luteinizing hormoneWOMEN: regulates estrogen secretion and ovum development; MEN: testosterone production
