骨骼在人的一生中是处于不断转换、重塑,以维持骨骼机械完整性的过程中的,骨骼重建包括破骨细胞降解基质的骨吸收,和成骨细胞形成基质的骨形成。在成人骨架中,新骨形成是骨重塑的主要结果。在小梁骨和皮质骨中,骨重塑来自骨重塑单位的骨吸收和骨形成的活性作用,结果以新骨代替 Bones in the life of a person is constantly changing, remodeling, in order to maintain the mechanical integrity of bone in the process of bone reconstruction, including osteoclast degradation matrix bone resorption, and osteoblast-forming bone formation. In the adult skeleton, new bone formation is a major result of bone remodeling. In trabecular and cortical bone, bone remodeling results from the bone resorption and bone formation activity of the bone remodeling unit, resulting in the replacement of the new bone with
