Nissl's granules are present in

Options

A. Cyton & axon
B. Cyton only
C. Dendrites & Cyton
D. Dendrites only

Answer

### Step-by-Step Solution:

1. **Understanding Nissl's Granules**: Nissl's granules are large granular bodies found in neurons. They are primarily composed of rough endoplasmic reticulum (RER) and free ribosomes.

2. **Function of Nissl's Granules**: The main function of Nissl's granules is to serve as a site for protein synthesis within the neuron.

3. **Location of Nissl's Granules**: Nissl's granules are found in two specific parts of the neuron: the cyton (cell body) and dendrites. They are not found in the axon.

4. **Analyzing the Options**: The question provides several options:
- Cyton and Exon
- Cyton only
- Dendrites and Cyton
- Dendrites only

5. **Identifying the Correct Option**: Since Nissl's granules are present in both the cyton and dendrites, the correct answer is the option that includes both these structures.

6. **Conclusion**: Therefore, the correct answer is "Dendrites and Cyton".

### Final Answer:
Nissl's granules are present in **Dendrites and Cyton**.
