Anatomy/FunctionBone Remodeling: ResorptionDespite its hardness, bone is always in a slow process of change, with old bone being broken down and new bone being made to replace it. In healthy bone, this process -- called bone "remodeling" or "turnover" -- occurs in two- to three-month cycles in such a way that the bone maintains its normal form, density, and strength. In bone remodeling, cells called osteoclasts dissolve (resorb) old bone cells, leaving tiny cavities behind. | |
