Questions from pre-lab quiz and post-lab quiz about hormone replacement therapy.
- 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.

- 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.
