Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Bone remodeling and repair depend on the balance between bone formation and bone resorption.
Step 2: Meaning
Osteoblasts are the cells responsible for bone formation and mineralization, whereas osteoclasts break bone down.
Step 3: Analysis
In elderly patients, the number and activity of osteoblasts typically decline, leading to a decreased ability to synthesize new bone matrix during the repair process.
Step 4: Conclusion
The reduction in osteoblast function is the primary reason for delayed or reduced bone healing in the elderly. Final Answer: (A)
