Neuronal degeneration is seen in all of the following, except



A Crush nerve injury

B Fetal development

C Senescence

D Neuropraxia

Ans. D Neuropraxia

Neuropraxia (nerve not working) is a local block to conduction of nerve impulses at a discrete area along the course of a nerve, axons are in continuity and therefore wallerian degeneration does not occur. It is a relatively mild injury and recovery is complete provided the cause is removed e.g. Qutch palsy.
