The Nissl's granules are present in
(a)Cell body
(b) Axon
(c ) Dendrites
(d) Glial cells

Options

A. a only
B. a, b and c
C. a and c
D. a , b, c and d

Answer

To solve the question regarding the presence of Nissl's granules, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Nissl's Granules**:
- Nissl's granules are structures found within neurons. They are primarily composed of rough endoplasmic reticulum (RER) and ribosomes, which are essential for protein synthesis.

2. **Identifying Neuron Structures**:
- Neurons consist of several parts:
- **Cell Body (Soma)**: Contains the nucleus and organelles, including Nissl's granules.
- **Dendrites**: Extensions of the neuron that receive signals; they also contain Nissl's granules.
- **Axon**: The long projection that transmits signals away from the cell body; it does not contain Nissl's granules.
- **Glial Cells**: Supportive cells in the nervous system that do not contain Nissl's granules.

3. **Analyzing the Options**:
- (a) Cell body: Contains Nissl's granules.
- (b) Axon: Does not contain Nissl's granules.
- (c) Dendrites: Contains Nissl's granules.
- (d) Glial cells: Do not contain Nissl's granules.

4. **Conclusion**:
- Nissl's granules are present in the cell body and dendrites of neurons. Therefore, the correct answer is option (c) A and C only.

### Final Answer:
The Nissl's granules are present in (a) Cell body and (c) Dendrites.
