  • 1. 
    Follicle-stimulating hormone (FSH)
    • A. 

      Is a steroid hormone.

    • B. 

      Stimulates ovarian follicle development.

    • C. 

      Is a posterior pituitary hormone secretion.

    • D. 

      Inhibits osteoclast activity and stimulates calcium uptake and deposition in long bones.


  • 2. 
    Estrogen
    • A. 

      Is produced by developing ovarian follicles.

    • B. 

      Is a peptide hormone.

    • C. 

      Is an anterior pituitary hormone secretion.

    • D. 

      Inhibits bone growth and, therefore, protects against the development of osteoporosis.


  • 3. 
    Calcitonin
    • A. 

      Stimulates osteoclast activity and inhibits calcium uptake into long bones.

    • B. 

      Is an anterior pituitary hormone secretion.

    • C. 

      Is a steroid hormone.

    • D. 

      Works against the development of osteoporosis.


  • 4. 
    Which of the following statements is true?
    • A. 

      The ovaries stop secreting estrogen after menopause.

    • B. 

      An untreated female's T score in anticipated to become more positive after menopause.

    • C. 

      Surgical removal of the ovaries will help limit the potential health problems associated with menopause.

    • D. 

      Osteoporosis is an increase in the density of porous long bones.


  • 5. 
    Saline injections were used in this experiment to measure the effect of
    • A. 

      A placebo on bone density.

    • B. 

      Large needles on the behavior of rats.

    • C. 

      Potassium chloride on bone density.

    • D. 

      Sodium chloride on bone density.


  • 6. 
    In the ovariectomized rats used in this experiment
    • A. 

      Estrogen levels were reduced because of the increased negative feedback caused by the injections.

    • B. 

      Estrogen levels were elevated because of the loss of negative feedback control.

    • C. 

      Osteoporosis was evident prior to the injections of estrogen.

    • D. 

      Follicle-stimulating hormone (FSH) levels were reduced because of the loss of negative feedback control.


  • 7. 
    Injection of calcitonin into an ovariectomized rat will
    • A. 

      Prevent goiter formation in this rat through its effect on negative feedback to the thyroid gland.

    • B. 

      Make the rat crave more milk and other calcium-rich beverages.

    • C. 

      Have no effect on bone density and, therefore, should be excluded from rat hormone-replacement therapies.

    • D. 

      Inhibit osteoclast activity and stimulate calcium uptake and deposition in long bones.


  • 8. 
    As the rat's bone density increases
    • A.
