Nissl body definition
The term "Nissl bodies" generally refers to discrete clumps of rough endoplasmic reticulum in nerve cells. Masses of rough endoplasmic reticulum also occur in some non-neuronal cells, where they are referred to as ergastoplasm , basophilic bodies, [1] or chromophilic substance.
