I am thoroughly confused on this subject! Checked the previous threads, and whatnot, but couldn't quite understand the explanations.
Basically, does PTH stimulate osteoclast activity? And since calcitonin is antagonistic, does it inhibit osteoclast activity? (And would the opposite system apply to osteoblasts?)
My reasoning is that PTH increases calcium levels in the blood, which means it induces osteoclast activity because osteoclasts break down bone and subsequently release calcium in the blood. And on the other hand, because calcitonin lowers calcium levels, it would inhibit osteoclast activity because there's no way for calcium to be released into the blood.
I'd love a layman-terms explanation. Thank you!
