![]() ![]() Responding to complex developmental signals, the matrix begins to calcify. In long bones, chondrocytes form a template of the hyaline cartilage diaphysis. All of the bones of the body, except for the flat bones of the skull, mandible, and clavicles, are formed through endochondral ossification. Osteoprogenitor cells are important in the repair of fractures.Įndochondral ossification is the process of bone development from hyaline cartilage. ![]() Osteoprogenitor cells are squamous stem cells that divide to produce daughter cells that differentiate into osteoblasts. Osteocytes maintain normal bone structure by recycling the mineral salts in the bony matrix. Osteocytes are mature bone cells and are the main cells in bony connective tissue these cells cannot divide. ![]() ![]() Bone may also be resorbed for remodeling, if the applied stresses have changed. These minerals, released from bones into the blood, help regulate calcium concentrations in body fluids. They remove bone structure by releasing lysosomal enzymes and acids that dissolve the bony matrix. Osteoclasts are large bone cells with up to 50 nuclei. Osteoblasts become trapped in these secretions and differentiate into less active osteocytes. Osteoblasts synthesize and secrete the organic part and inorganic part of the extracellular matrix of bone tissue, and collagen fibers. Osteoblasts are bone cells that are responsible for bone formation. \): Trabeculae in spongy bone are arranged such that one side of the bone bears tension and the other withstands compression.īone consists of four types of cells: osteoblasts, osteoclasts, osteocytes, and osteoprogenitor cells. ![]()
