bone deposition的意思|示意

'

Bone deposition，即骨质沉积，是骨骼生长发育过程中重要的一个步骤，即通过骨质沉积来形成新的骨骼组织。 骨质沉积是一种典型的“加/分解”作用，其含义是在原有的骨基础上发生的骨骼的组织形态的变化，可以使得原有的骨骼组织结构发生变化和改善。 沉积过程包括了2种作用： 首先是骨细胞产生新的骨组织，即新骨形成，随着新骨细胞分化，最终能够形成完整的新骨结构，新骨与原有骨结构融合； 其次是原有骨骼的重组，在这个过程中，由于骨质的有限性，原有的骨骼减少，但总的骨量保持不变，也就是说，在新骨形成的同时，会出现原有骨的重组。

Bone deposition is an important step in the development and growth of bones, which forms new bone tissue by depositing bone. Bone deposition is a typical \\"addition/decomposition\\" action, which means that the original skeletal structure will change and be improved on the basis of the original bone. The deposition process includes two roles: first, bone cells produce new bone tissue, i.e. new bone formation, and with the differentiation of new bone cells, a complete new bone structure can finally be formed, and the new bone will merge with the original bone structure; secondly, the reorganization of the original bone, in this process, due to the limited bone density, the original bone will reduce, but the total bone volume remains unchanged, that is, while the new bone is formed, the reorganization of the original bone will occur.
