Question

a) nerve stimulation

b) antidiuretic hormone

c)Vitamin D

d)repeated external loading (mechanical stress)

Answer 1

answer is D

Answer 2

See Wolff's law...

Answer 3

I find that the best way to look for an answer to a question that I'm not sure about is to eliminate the obvious wrong ones.

First- We can KNOW that it is NOT antiduretic hormone because that is a hormone produced by the hypothalamus which simulates the kidneys to reabsorb more water and reducing urine volume.

Second- Calcium absorbtion is related to blood levels of ionic calcuim which is regulated by Vitamin D, which acts as a cofactor to facilitate active calcuim absorption

Now, thats all I know off the top of my head but when I looked it up in my Anatomy book, it says that Leptin is is the hormone that stimulates bone remodeling as well as RESPONSE TO MECHANICAL STRESS. So, the answer would be, D.
