Question

In nerve cells, E.R. forms:

• A. Myeloid bodies
• B. Neurotubules
• C. Nissl's granules
• D. Neurofilaments

Answer 1

The correct option is C

Nissl's granules

The correct option is C:

Explanation of the correct option:

Option C:

1. Nissl's granules are large and irregular masses of ribosomes and RER (Rough Endoplasmic Reticulum).
2. They're absent in the axon.
3. The function of Nissl's granules includes protein synthesis in the body of neurons.
4. In nerve cells, E.R. ( Endoplasmic Reticulum) forms Nissl's granules.

Explanation of the incorrect option:

Option A:

Myeloid bodies are organized structural forms of the smooth endoplasmic reticulum.

Option B:

Neurotubules help in maintaining the shape of the neuron.

Option D:

Neurofilaments help in the maintenance and support of the cytoskeleton.

Final answer: In nerve cells, E.R. forms Nissl's granules.
