There are three special types of cells that are found only in the bone. These cell names all start with OSTEO because that is the Greek word for bone. OSTEOCLASTS are large cells that dissolve the bone. They come from the bone marrow and are related to white blood cells.
8 Cells Associated with Bone Tissue osteoprogenitor cells: derived from mesenchyme these differentiate into osteoblasts. osteoblasts: bone forming cells which secrete the osteoid and then calcify it.osteoclasts: bone resorbing cells derived from monocytes.The cells found in bone tissue reflect the processes of remodeling and maintenance which go on constantly. In remodeling, first osteoclasts remove bone tissue, an osteon at a time.Next osteoblasts build up new bone to replace the old. Then the osteoblasts become osteocytes, mature bone cells which maintain the matrix. In this way the structural and functional integrity of the bone is maintained. Bone Tissue Matrix: collagen fibersproteoglycans (glycoproteins)Hydroxyapatite: inorganic salt of calcium and phosphorus Bone tissue (osseous tissue) differs from cartilage in having a solid matrix due to the presence of inorganic salts of calcium and phosphorus. These enable bone to have a rigid shape.
