Biology - Neural Control and Coordination Question with Solution | TestHub

Nissl's granules are large granular bodies found in the cell body and dendrites of neurons. They are composed of rough endoplasmic reticulum (RER) and free ribosomes.

Since ribosomes are made up of RNA and proteins, Nissl's granules are considered riboprotein components. Their primary function is the synthesis of proteins for the neuron.

They do not synthesize the myelin sheath (which is done by Schwann cells and oligodendrocytes), do not directly transmit nerve impulses, and are present in dendrons but absent in the axon and axon hillock.

Answer: These are riboprotein components.
