What type of cells are typically involved in the resorption phase of bone remodeling?

• A. Osteocytes
• B. Osteoblasts
• C. Osteoclasts
• D. Lining cells

Answer: (C)

The correct answer is osteoclasts, as these specialized cells play a crucial role in the resorption phase of bone remodeling. During this phase, osteoclasts break down old or damaged bone tissue, a process essential for maintaining healthy bone structure and function. This activity helps to release calcium and other minerals back into the bloodstream, regulating mineral balance in the body.

Osteoblasts are responsible for bone formation, creating new bone tissue in the remodeling process, while osteocytes serve to maintain bone tissue and regulate mineral content. Lining cells, on the other hand, line the surfaces of the bones and are involved in the protection and maintenance of the bone surface but do not directly participate in the resorption of bone. Therefore, the involvement of osteoclasts is critical in the resorption phase as the primary cells tasked with this function.
