Which of the following is not a part of brain stem of human brain?

Options

A. Mid brain
B. Pons
C. Medulla oblongata
D. Cerebellum

Answer

To solve the question "Which of the following is not a part of the brain stem of the human brain?", we will analyze the options provided and identify which one does not belong to the brain stem.

### Step-by-Step Solution:

1. **Understanding Brain Structure**: The human brain is divided into several parts, including the forebrain, midbrain, and hindbrain. The brain stem is primarily composed of the midbrain, pons, and medulla oblongata.

2. **Identifying the Options**: The options given are:
- Midbrain
- Pons
- Medulla Oblongata
- Cerebellum

3. **Analyzing Each Option**:
- **Midbrain**: This is a part of the brain stem, located between the forebrain and hindbrain.
- **Pons**: This is also a part of the brain stem, connecting different parts of the brain and involved in regulating functions such as sleep and respiration.
- **Medulla Oblongata**: This is another component of the brain stem, responsible for controlling vital functions like heart rate and breathing.
- **Cerebellum**: This structure is located at the back of the brain and is primarily involved in coordination and balance, but it is not part of the brain stem.

4. **Conclusion**: Since the cerebellum is not a part of the brain stem, the correct answer to the question is **Cerebellum**.

### Final Answer:
Cerebellum is not a part of the brain stem of the human brain.
