Which of the following is the part of mid brain?

Options

A. Cerebrum
B. Diencephalon
C. Corpora quadrigemina
D. None of these

Answer

To determine which part of the brain is part of the midbrain, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Brain**: The brain is divided into three main parts: the forebrain, midbrain, and hindbrain. Each of these parts has distinct structures and functions.

2. **Identify the Options**: The options provided are:
- Cerebrum
- Diencephalon
- Corpora Quadrigemina

3. **Analyze Each Option**:
- **Cerebrum**: This is the largest part of the brain and is part of the forebrain. It is responsible for higher brain functions such as thought and action. Therefore, it is not part of the midbrain.
- **Diencephalon**: This is also part of the forebrain and is located between the telencephalon and midbrain. It includes structures like the thalamus and hypothalamus. Hence, it is not part of the midbrain.
- **Corpora Quadrigemina**: This structure is located in the midbrain and consists of four colliculi (two superior and two inferior). It serves as a reflex center for vision and hearing.

4. **Conclusion**: Based on the analysis, the correct answer is **Corpora Quadrigemina**, as it is the only option that is part of the midbrain.

### Final Answer:
**Corpora Quadrigemina**
