Regeneration of cartilage is carried on by:
Correct answer: D. Matrix
- A. Collagenous fibers
- B. Blood vessels
- C. Perichondrium
- D. Matrix
Explanation
The correct answer is the 'Matrix.' The matrix is essential for the regeneration of cartilage as it provides a scaffold for cellular attachment, growth, and communication. While collagenous fibers and the perichondrium contribute to the structure and minor repair, they are not the main agents of regeneration. Blood vessels, being absent in cartilage, play no role in its regeneration.
