How does osteoclasts work
WebOsteoclasts are giant cells containing between 10 and 20 nuclei. They closely attach to the bone matrix by binding its surface integrins to a bone protein called vitronectin. This close apposition seals off an area of the bone beneath the osteoclast and allows the osteoclast to form a microenvironment that resorbs bone. WebThe cell type, which facilitates break down of a bone, is the ‘osteoclasts’. When looking at the cross section of a bone, the outermost layer is termed as the ‘cortical zone’ while the inner zone of the bone is given the name, ‘trabecular’ or ‘spongy’ zone. ... which indicates its ability to perform energy demanding work such as ...
