Good video. One mistake is about parathyroid hormone. PTH actually doesn't affect osteoclasts at all as they have no PTH receptors. It affects the osteoblasts, which control the osteoclasts. At a low continuous dose of PTH in the body, the osteoblasts will secrete M-CSF and express RANK-L which stimulates the osteoclasts to break down bone. The RANK-L (ligand) on osteoblasts binds to RANK (receptor) on the osteoclasts to stimulate them. In addition, estrogen will affect the osteoblasts mainly. It downregulates RANK-L and decreases M-CSF expression. It also allows osteoblasts to create osteoprotegerin (OPG) which is a decoy receptor for RANK-L on osteoblasts, which decreases stimulation of RANK on osteoclasts. This all leads to increases bone formation from estrogen.

Thank you for this wonderfully detailed video. But I couldn't agree with you regarding the origin of the osteoclasts. As far as I know osteoclasts are derived from macrophages.

theadrinka86 Not at all. I used this channel, decks, and a book called, "Dental Board Busters", that my classmate recommended. These resources were thorough, but not just the decks; they are good for general questions, but not for the small details within content.

Osteoprogenitor cells do not give rise to osteoclasts. Osteoclasts come from macrophages.

+aznpercussionboy that's right, reading my textbook it states, "Osteoclasts originate within the red bone marrow monocyte/macrophage lineage."

amazing video.... but one correction is needed... PTH actually acts on osteoblast as it has receptor for the hormone.... and further this hormone stimulates osteoclast..... PTH does Not directly act on osteoclast...

Osteoblast and not osteoclasts have specific surface receptors for agent , such as 1,25-dihydroxy vitamin D3 and parathyroid hormone. So osteoclast in culture, which are therefore not in contact with osteoblast, do not respond to these agents.......please donot make mistakes.
