Thermoregulatory centre in brain of man is

Options

A. pituitary
B. diencephalon
C. hypothalamus
D. none of these

Answer

**Step-by-Step Solution:**

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

2. **Definition of Thermoregulatory Center**: The thermoregulatory center is a specific area in the brain that maintains the body’s temperature through homeostasis. It adjusts the body temperature in response to varying external conditions, such as heat or cold.

3. **Identifying the Options**: The options given are:
- A) Pituitary
- B) Diencephalon
- C) Hypothalamus
- D) None of these

4. **Analyzing Each Option**:
- **Pituitary**: This is a gland that releases hormones but does not regulate body temperature. Therefore, it is not the correct answer.
- **Diencephalon**: This is a larger brain region that includes several structures, including the hypothalamus. However, it is not specific to thermoregulation.
- **Hypothalamus**: This is the specific part of the brain that acts as the thermoregulatory center. It is responsible for maintaining body temperature.
- **None of these**: This option implies that none of the previous answers are correct, which is not the case.

5. **Conclusion**: The correct answer is the hypothalamus, as it is the specific part of the brain responsible for thermoregulation.

**Final Answer**: C) Hypothalamus
