Question

why nissl's granules are absent in axon? ​

Answer 1

Answer:

Nissl bodies are nodal points in the endoplasmic reticulum, which permeate the cell body and dendrites. They are absent at the axon and axon hillock (Noback and Demarest, 1981). Hence their absence in neurons could negatively affect their functions.
