Neurapraxia is a nerve injury where the myelin around the nerve is locally damaged but the axon remains intact. This demyelination slows down or blocks conduction across the affected segment, yet there is no axonal disruption, so distal continuity is preserved and Wallerian degeneration does not occur. Recovery happens as the myelin is restored (remyelination) over days to weeks.

That’s why the statement describing slowed conduction due to segmental demyelination with the axon intact is the best description. The other scenarios imply axonal damage or nerve transection, which would involve Wallerian degeneration or complete discontinuity, not neurapraxia.
