The correct Answer is:
To solve the question regarding the correct sequence of meninges from inside to outside, we will follow these steps: 1. **Understand the Meninges**: The meninges are protective membranes that cover the brain and spinal cord. There are three layers of meninges: the pia mater, the arachnoid membrane, and the dura mater. 2. **Identify the Layers**: - **Pia Mater**: This is the innermost layer that is directly attached to the surface of the brain and spinal cord. - **Arachnoid Membrane**: This is the middle layer that lies above the pia mater. - **Dura Mater**: This is the outermost layer that is tough and protective, lying beneath the bones of the skull and vertebral column. 3. **Sequence from Inside to Outside**: Based on the identification of the layers: - The first layer (innermost) is the **Pia Mater**. - The second layer is the **Arachnoid Membrane**. - The third layer (outermost) is the **Dura Mater**. 4. **Select the Correct Option**: The correct order from inside to outside is: - Pia Mater → Arachnoid Membrane → Dura Mater This corresponds to option (c). 5. **Conclusion**: Therefore, the correct answer is (c) Pia Mater → Arachnoid Membrane → Dura Mater.
