Nissl granule (medicine)


Nissl granule
<cell biology> Discrete clumps of material seen by phase contrast microscopy in the perikaryon of some neurons, particularly motor neurons.

They are basophilic and contain much RNA, are actually regions very rich in rough endoplasmic reticulum. Their reaction following damage to neurons is characteristic, they disperse through the cytoplasm giving a general basophilia to the whole cell body.
