Solution
The correct option is D Nissl’s granules Nissl’s granules are deeply stained particles present in the neuroplasm. They are irregular masses of the rough endoplasmic reticulum (RER) and free ribosomes which are sites of the protein synthesis.
Schwann cells are neuroglial cells that produce myelin sheath which acts as an electrical insulator.
Neurofibrils are fine fibres in the neuroplasm that play a role in the transport of various substances.
Synapse is the point of contact between two neurons through which the nerve impulses are transmitted from one neuron to the other.
