Wallenberg degeneration is seen in______________?
Correct answer: A. Distal cut end of nerve without cell body
- A. Distal cut end of nerve without cell body
- B. Proximal cut end of nerve with cell body
- C. Both the free ends of the cut nerve
- D. All are true
Explanation
Wallerian degeneration occurs in the distal part of a severed axon, which is disconnected from its cell body and therefore loses trophic support. The proximal segment usually survives, although it may later sprout during regeneration.
