Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Bone undergoes continuous remodeling through two types of cells:
- Osteoblasts: These cells build new bone matrix (bone formation).
- Osteoclasts: These cells break down bone matrix (bone resorption).
- Osteocytes: Mature bone cells involved in sensing mechanical stress and regulating remodeling.
- Osteocalcin: A hormone produced by osteoblasts—not a cell.
Bone resorption is the process by which minerals and collagen are removed from the bone, making way for new bone formation. This role is specifically performed by osteoclasts, which secrete acids and enzymes to dissolve bone tissue.
Thus, the correct answer is Option (B) Osteoclasts.
- Osteoblasts: These cells build new bone matrix (bone formation).
- Osteoclasts: These cells break down bone matrix (bone resorption).
- Osteocytes: Mature bone cells involved in sensing mechanical stress and regulating remodeling.
- Osteocalcin: A hormone produced by osteoblasts—not a cell.
