Which term describes bone-forming cells?

• A. Osteoclast
• B. Osteoblast
• C. Ossification
• D. Osteocyte

Answer: (B)

Bone-forming cells are osteoblasts. They arise from mesenchymal cells and sit on bone surfaces, where their main job is to synthesize and secrete the organic bone matrix (osteoid), rich in collagen type I, and to promote mineralization by attracting calcium and phosphate. As they lay down matrix and become embedded within it, osteoblasts can mature into osteocytes, the cells that maintain bone tissue. Osteoclasts are the cells that resorb bone, and ossification refers to the process of bone formation, not a cell type.
