Which cells are primarily responsible for building bone?

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

Answer: (B)

The cells primarily responsible for building bone are osteoblasts. These specialized cells play a crucial role in bone formation by synthesizing and secreting the bone matrix, which includes collagen and other proteins. Osteoblasts are involved in the mineralization process, where they help deposit calcium and phosphorus into the bone matrix, ultimately contributing to the strength and density of bones. Osteocytes, while important in maintaining bone health and communication between different cells, are not directly involved in the formation of new bone tissue. They originate from osteoblasts that have become embedded in the bone matrix. Osteoclasts, on the other hand, are responsible for bone resorption, breaking down bone tissue to release minerals back into the bloodstream. Chondrocytes are primarily involved in the development of cartilage, which is a precursor to bone during the growth process, but they do not build bone themselves. Thus, the role of osteoblasts is central to the formation and mineralization of bone tissue.
