cell metabolites
fat granules
ribosomes
mitochondria
Solution
Nissl's granules are the substances found in the neurons which are a large granular type of body. These granules are very useful for protein synthesis also help to transport these proteins to the cyton.
Related Theory
Nissl's granules are present in the cytoplasm of the cell body of the neurons and dendrites along with other cell organelles like Golgi apparatus, endoplasmic reticulum, mitochondria, nucleus, etc. These granules give a slight coloured appearance to the cytoplasm of the cell body.
