Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which statement is true about Nissl granules?
A
So RNA.
B
Works to produce protein.
C
There are many in the axon hillocks.
D
A group of mitochondria that stick together.
Explanation: 

Detailed explanation-1: -Similar to the ergastoplasm of glandular cells, Nissl bodies are the main site of protein synthesis in the neuronal cytoplasm. The ultrastructure of Nissl bodies suggests they are primarily concerned with the synthesis of proteins for intracellular use.

Detailed explanation-2: -Nissl’s granules are found in the cyton or cell body of the neurons. Function: Nissl’s granule helps in the protein synthesis of neurons. They also help in the transport of protein.

Detailed explanation-3: -A Nissl body, also known as Nissl or tigroid substance, is a large granular body found in neurons. These granules are concentrated rough endoplasmic reticulum (RER) with rosettes of free ribosomes and are the site of protein synthesis. Thus, the correct answer is option D.
