Question 1

Attaining one's genetic limit for bone mineral content at the time of peak bone mass is widely accepted as a primary prevention strategy for reducing the risk of developing osteoporosis.

Accepted Answer

Attaining one's genetic limit for bone mineral content at the time of peak bone mass is indeed widely accepted as a primary prevention strategy for reducing the risk of developing osteoporosis. This can be achieved through a combination of factors, including adequate calcium and vitamin D intake, regular weight-bearing exercise, and avoiding lifestyle habits such as smoking and excessive alcohol consumption that can accelerate bone loss.

Question 2

What is the physiological consequence of humans' ability to remodel bone?

Accepted Answer

The answer of What is the physiological consequence of humans'...

Question 3

The effect of estrogen on bone metabolism is to:

Accepted Answer

Estrogen stimulates osteoblastic activity, leading to an increase in bone formation and density.

Question 4

The loss of estrogen in postmenopausal women has what effect on bone?

Accepted Answer

The answer of The loss of estrogen in postmenopausal women...

Question 5

The bone cells responsible for resorption of hydroxyapatite are the osteoblasts.

Accepted Answer

The bone cells responsible for resorption of hydroxyapatite are the osteoclasts, not the osteoblasts. Osteoblasts are responsible for forming new bone tissue.

Question 6

Increasing the dietary intake of calcium has not,in general,been an effective method of increasing bone mineral content in postmenopausal women.

Accepted Answer

While calcium is important for bone health, studies have shown that simply increasing dietary intake of calcium does not necessarily lead to increased bone mineral content in postmenopausal women. Other factors, such as exercise and vitamin D levels, also play a crucial role in maintaining bone health.

Question 7

The prevalence of osteoporosis is the same in men and women of similar age.

Accepted Answer

Osteoporosis is more prevalent in women than men due to differences in bone density and hormonal changes. Women also typically live longer, which increases their risk of developing osteoporosis over time.
