The success of peripheral nerve regeneration is most dependent on which factor?
Show answer and explanation
Correct answer: Proximity to the cell body and stump alignment
Injuries closer to the cell body have a higher risk of neuronal death. Furthermore, if the proximal and distal stumps are not well-aligned, the regenerating axons cannot find their way into the distal tubes, leading to failure.
