Thermo regulatory center in human brain is :

Options

A. Pituitary
B. Diencephalon
C. Hypothalamus
D. None

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for the thermoregulatory center in the human brain. We need to identify which part of the brain is responsible for regulating body temperature.

2. **Analyzing the Options:**
The options provided are:
- Pituitary
- Diencephalon
- Hypothalamus

3. **Evaluating the Pituitary Gland:**
- The pituitary gland is known for its role in growth and development through the secretion of hormones.
- It does not have a direct role in temperature regulation.
- **Conclusion:** The pituitary gland is not the answer.

4. **Evaluating the Diencephalon:**
- The diencephalon serves as a primary relay and processing center for sensory information and autonomic control.
- While it plays a significant role in various functions, it is not specifically responsible for thermoregulation.
- **Conclusion:** The diencephalon is not the answer.

5. **Evaluating the Hypothalamus:**
- The hypothalamus is crucial for maintaining homeostasis, including regulating body temperature.
- It controls the diameter of blood vessels and manages mechanisms such as shivering and sweating to maintain a constant body temperature.
- **Conclusion:** The hypothalamus is the thermoregulatory center of the human brain.

6. **Final Answer:**
Therefore, the thermoregulatory center in the human brain is the **Hypothalamus**.
