The layer of cells which covers the cerebral hemisphere is called:

Options

A. Piamater
B. Duramater
C. Cerebral cortex
D. Both A and B

Answer

To answer the question "The layer of cells which covers the cerebral hemisphere is called:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking for the specific layer of cells that covers the cerebral hemispheres of the brain.

2. **Evaluate the Options**: We need to consider the provided options:
- **Option A**: Not specified in the transcript.
- **Option B**: Dura mater
- **Option C**: Cerebral cortex
- **Option D**: Both A and B

3. **Analyze Each Option**:
- **Dura Mater**: This is a tough outer layer of the meninges that surrounds the brain and spinal cord. It is not the layer that covers the cerebral hemisphere directly, as it is attached to the skull.
- **Cerebral Cortex**: This is the outer layer of the brain, composed of gray matter, and is indeed the layer that covers the cerebral hemispheres. It is responsible for many higher brain functions, including thought, memory, and consciousness.
- **Both A and B**: Since we have already established that the dura mater does not cover the cerebral hemisphere, this option cannot be correct.

4. **Conclusion**: Based on the analysis, the correct answer is **Cerebral Cortex** (Option C), as it is the layer of cells that covers the cerebral hemispheres.

### Final Answer:
The layer of cells which covers the cerebral hemisphere is called the **Cerebral Cortex**.
