<prompt> Which of the following is false about peripheral nerve injury?Neuropraxia is irreversibleEpineurium is intact in axonotmesisNeurotmesis is the most severe form of injuryWellerian generation starts in axonotmesis  <response>: Ans. is a i.e., Neuropraxia is irreversible Seddons classification of peripheral nerve in juryNeurapraxia Class Io 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 ischemiao No Wallerian degeneration is seen.Axonotmesis Class IIo This is a more severe nerve injury with disruption of the neuronal axon, but with maintenance of the epineurium.This type of nerve damage may cause paralysis of the motor,sensory, and autonomic. Mainly seen in crush injuryo Wallerian degeneration occurs.Neurotmesis Class IIIo Neurotmesis is the most severe lesion with no potential of full recovery. It occurs on severe contusion, stretch, laceration, or Local Anesthetic Toxicity. The axon and encapsulating connective tissue lose their continuity. Thelast extreme degree of neurotmesis is transsection.
