Which cell type maintains bone tissue?

Which cell type maintains bone tissue?

• A. Osteoblasts
• B. Osteocytes
• C. Osteoclasts
• D. Fibroblasts

Answer: (B)

The one that maintains mature bone tissue are osteocytes. These are mature bone cells embedded inside the mineralized matrix in spaces called lacunae, with tiny extensions reaching through canaliculi to communicate with neighboring cells. Their real job is to monitor the health and mechanical load of the bone and coordinate remodeling by signaling to osteoblasts and osteoclasts when bone should be formed or resorbed, helping to preserve bone structure and mineral balance. Osteoblasts build new bone on surfaces, osteoclasts break down bone during remodeling, and fibroblasts are connective tissue cells not specialized for maintaining bone tissue.
