Physiology of the Osteoclast

The video tutorial explores the roles of osteoblasts, osteocytes, and osteoclasts in bone tissue. It explains the differentiation of osteoblasts from osteoprogenitor cells and their function in bone deposition. The focus then shifts to osteoclasts, which originate from macrophages and are responsible for bone resorption. The video details the structure and function of osteoclasts, including their ruffled border and the enzymes involved in degrading bone tissue. Finally, it discusses the hormonal regulation of osteoclast activity and its impact on blood calcium levels.
