Detailed explanation-1: -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, or chromophilic substance.
Detailed explanation-2: -There are clusters of rough endoplasmic reticulum (not shown in Figure 1) that are called Nissl bodies or are sometimes referred to as chromatophilic substances. The dendrite is typically a short, abundantly branched, slender process (extension) of the cell body that receives stimuli.
Detailed explanation-3: -Subcellular structures found in nerve cell bodies and DENDRITES. They consist of granular endoplasmic reticulum (ENDOPLASMIC RETICULUM, ROUGH) and RIBOSOMES.
Detailed explanation-4: -Rough endoplasmic reticulum (RER) and smooth endoplasmic reticulum (SER) are the two types of endoplasmic reticulum. Nissl granules are formed from rough endoplasmic reticulum (RER). RER has attached ribosomes, whereas SER has no attached ribosomes.
