production of new bony matrix is by which cell type
Bone tissue Osteoblasts are bone cells that are responsible for the formation of new bone. Osteoblasts deposit a collagen matrix and release minerals that combine to make the bone mineral. Unlike the much larger osteoclasts, osteoblasts are much smaller; they only have one nucleus. Osteoblasts also group to form new bone. Osteoblasts are important because they allow the bones to be made, remodeled, and repaired. The osteoblasts come from the differentiation of osteogenic cells in the tissue that covers the outside of the bone, or the periosteum and the bone marrow.[6] The osteoblast creates and repairs new bone by actually building around itself. First, the osteoblast puts up collagen fibers. These collagen fibers are used as a framework for the osteoblasts' work. The osteoblast then deposits calcium phosphate which is hardened by hydroxide and bicarbonate ions. The brand new bone created by the osteoblast is called osteoid.[7] Once the osteoblast is finished working it is actually trapped inside of the bone once it hardens. When the osteoblast becomes trapped, it becomes known as an osteocyte.[8] Other osteoblasts remain on the top of the new bone and are used to protect the underlying bone, these become known as lining cells.
