Options

A. Duramater `rarr` arachnoid membrane `rarr` piamater
B. Duramater `rarr` piamater `rarr` arachnoid membrane
C. Piamater `rarr` arachnoid membrane `rarr` duramater
D. Arachnoid member `rarr` duramater `rarr` piamater

Answer

To determine the correct sequence of the meninges from the inner to the outer side, we need to understand the structure of the meninges that protect the brain and spinal cord.

### Step-by-Step Solution:

1. **Identify the Meninges**: The meninges consist of three layers:
- **Pia Mater**: This is the innermost layer that is directly attached to the surface of the brain and spinal cord.
- **Arachnoid Mater**: This is the middle layer that lies between the pia mater and the dura mater.
- **Dura Mater**: This is the outermost layer that provides the most protection.

2. **Sequence from Inner to Outer**:
- Starting from the innermost layer, we have the **Pia Mater**.
- Next, we move to the **Arachnoid Mater**.
- Finally, the outermost layer is the **Dura Mater**.

3. **Final Sequence**: Therefore, the correct sequence of the meninges from inner to outer is:
- **Pia Mater** → **Arachnoid Mater** → **Dura Mater**.

4. **Conclusion**: The correct answer is that the meninges are arranged in the order of Pia Mater, Arachnoid Mater, and Dura Mater from the inner side to the outer side.
