Which of the following is false about
peripheral nerve injury?
a) Neuropraxia is irreversible
b) Epineurium is intact in axonotmesis
c) Neurotmesis is the most severe form of injury
d) Wellerian generation starts in axonotmesis
Correct Answer - A
Ans. A. Neuropraxia is irreversible
Neuropraxia (Class l)
This is the least severe form of nerve injury, with complete recovery.
In this case, the axon remains intact, but there is myelin damage
causing an interruption in conduction of the impulse down the nerve
fiber.
Most commonly, this involves compression of the nerve or disruption
to the blood supply (ischemia).
No Wallerian degeneration is seen.
