Ger. neurologist, 1860–1919.

Nissl body

Large granular bodies found in nerve cells. They can be demonstrated by selective staining. They are rough endoplasmic reticulum (with ribosomes) and are the site of protein synthesis. Nissl bodies show changes under various physiological conditions, and in pathological conditions they may dissolve and disappear (chromatolysis).
Synonym: Nissl granule See: tigroid bodies.

Nissl degeneration

Nerve cell degeneration after division of the axon.

Nissl granule

Nissl body.
