Which region of human brain helps in maintaining the constant body temperature ?

Options

A. Medulla
B. Cerebrum
C. Cerebellum
D. Hypothalamus

Answer

To solve the question of which region of the human brain helps in maintaining constant body temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which part of the human brain is responsible for regulating body temperature.

2. **Review the Options**: The options provided are:
- Medulla
- Cerebrum
- Cerebellum
- Hypothalamus

3. **Analyze Each Option**:
- **Medulla**: This part of the brain is primarily involved in regulating autonomic functions such as heart rate and respiration. It does not play a significant role in temperature regulation.
- **Cerebrum**: The cerebrum is responsible for higher brain functions such as thought, action, and sensory processing. It does not directly regulate body temperature.
- **Cerebellum**: The cerebellum is mainly involved in coordination and balance. It does not have a role in maintaining body temperature.
- **Hypothalamus**: The hypothalamus is a small region of the brain that plays a crucial role in many bodily functions, including the regulation of body temperature. It acts as the body's thermostat, detecting changes in temperature and initiating responses to maintain a stable internal environment.

4. **Conclusion**: Based on the analysis, the correct answer is the **Hypothalamus**, as it is the region of the brain responsible for maintaining constant body temperature.

### Final Answer:
The region of the human brain that helps in maintaining constant body temperature is the **Hypothalamus**.
