Author: Sanketh DS, MDS
Bone is a specialised form of connective tissue that consists of cells and intercellular material. Osteoblasts, osteocytes and osteoclasts make up the cells of the bone, while the inter-cellular material is made of organic and inorganic material. By dry weight, bone comprises of 33% organic matrix, with 28% representing type I collagen, and non-collagenous proteins like bone sialoprotein, osteocalcin,osteopontin, osteonectin and proteoglycans making up 5%. The organic matrix is mineralized by hydroxyapatite (inorganic material), which comprises the rest of the 67% of bone by dry weight.
