What role do osteoblasts play in bone formation?

• A. They inhibit bone resorption
• B. They digest old bone
• C. They lay down new bone until resorbed bone is completely replaced
• D. They regulate calcium levels

Answer: (C)

Osteoblasts play a crucial role in bone formation by laying down new bone. These specialized cells are responsible for synthesizing and secreting the bone matrix, which is primarily composed of collagen and other proteins. As osteoblasts create this matrix, they produce minerals such as calcium and phosphate that contribute to bone mineralization, transforming the soft, newly formed matrix into hard bone material. In the process of bone remodeling, osteoblasts work in conjunction with osteoclasts, the cells that break down old bone tissue. While osteoclasts resorb or digest the older bone, osteoblasts are active in creating new bone until the resorbed bone is completely replaced. This dynamic process is essential for maintaining healthy bone structure and strength, as well as for the repair of any damage that may occur. Understanding the function of osteoblasts in synthesizing new bone material sheds light on the overall process of bone health and density, which is especially significant in the context of bone densitometry assessments.
