First change to occur in the distal segment of cut________________?
Correct answer: B. Axonal degeneration
- A. Myelin degeneration
- B. Axonal degeneration
- C. Mitosis of schwann cell
- D. Sprouting
Explanation
The axon in the distal segment degenerates first after nerve severance, followed by breakdown of its myelin sheath and later Schwann-cell proliferation and sprouting. Thus axonal degeneration is the earliest listed change.
