In this video, we discuss the following: <br/>
[1] functions of osteoclasts and how they promote bone<br/> resorption
[2] production of osteoc<br/>lasts from macrophages
[3] appeara<br/>nce of osteoclasts by Scanning EM

In this video, we will contrast the biological/hormonal responses to low and high blood calcium and determine the effects on bone mineral density.

In this video, we discuss the following: <br/>
[1] functions of osteoblasts and<br/> osteocytes
[2] orga<br/>nization of the osteon
