How does gravity affect bone remodeling
WebBone formation occurs by osteoblasts secreting an organic matrix (osteoid) and then mineralizing the matrix. When the remodeling process is skewed such that, over time, there is more eating than replenishing, you get osteoporosis. When the remodeling process is aborted, say in avascular necrosis, bad bone accumulates. (Seen here as density). WebOct 5, 2016 · Bone remodeling also plays a role in the maintenance of acid/base balance, and the release of growth factors embedded in bone. Moreover, it provides a reservoir of labile mineral (short-term homeostasis) and it is the only mechanism by which old, dying, or dead osteocytes can be replaced [Dempster, 2006]. Bone modeling
