Which of the following endocrine functions are responsible for increased resorption of bone that results in a reduction of the number and function of osteoclasts? Select all that apply
A)
Calcitonin secretion
B)
Decrease in estrogen levels
C)
Stimulation of excess thyroid hormone
D)
Release of catecholamines
E)
Increase movement of calcium and phosphate from bone into the extracellular fluid
Ans:
A, B
Feedback:
Parathyroid hormone increases the number of resorptive function of the osteoclasts. Calcitonin is thought to reduce the number and resorptive function of the osteoclasts. Estrogen also reduces the number and function of the osteoclasts. Thus, the decrease in estrogen levels that occurs at menopause results in increased resorption of bone. Release of catecholamines has no influence over osteoclast function. Increased movement of calcium and phosphate from bone into extracellular fluid is regulated by parathyroid hormone.
