Questions and Answers

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.
  
  The X-ray scanning assay reports a more-negative T-score
- B.
  
  The rat requires a higher dose of hormones to be injected for adequate therapy.
- C.
  
  The X-ray scanning assay reports a less-negative T-score.
- D.
  
  The rat requires more gaseous anesthetic to remain immobilized.
