First to occur after a sharp nerve cut ?
a) Chromatolysis
b) Polymorphic arrangement
c) Increased protein synthesis
d) Macrophage activation

Correct Answer - A
Ans. A. Chromatolysis
Within 6 hours of injury, the nucleus migrates to the periphery of the
cell where Nissl’s granules and rough endoplasmic reticulum break
up and disperse.
This phenomenon is called chromatolysis.
The part of nerve distal to the point injury undergoes ‘secondary or
Wallerian degeneration’, the proximal part undergoes “primary or
retrograde” degeneration up to a single node Ranvier.
