In a peripheral nerve lesion, there is no reaction of degeneration. This indicates that recovery will take place in

Explanation:
When a peripheral nerve injury shows no reaction of degeneration, the axon itself is intact. This is neuropraxia, where the conduction block is mainly from temporary demyelination rather than axonal damage. Because the axon doesn’t degenerate distal to the lesion, recovery comes mainly from remyelination of the affected segment, which happens relatively quickly—typically within about 2–4 weeks. If degeneration were present (Wallerian degeneration), recovery would depend on axonal regrowth along the nerve, which takes much longer and is often months, depending on distance to the target.
