Which of the following keeps our body temperature at roughly `37^(@)` C by means of a complex thermostat system ?

Options

A. Somatosensory area
B. Hypothalamus
C. Basal ganglia
D. Cerebellum

Answer

To solve the question regarding which part of the body keeps our temperature at roughly 37°C by means of a complex thermostat system, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Options**: The question provides four options:
- A) Somatosensory area
- B) Hypothalamus
- C) Basal ganglia
- D) Cerebellum

2. **Understand the Function of Each Option**:
- **Somatosensory Area**: Located in the parietal lobe of the brain, it is primarily responsible for processing sensory information such as touch, pressure, and temperature. However, it does not regulate body temperature.
- **Hypothalamus**: This is a crucial part of the brain that plays a significant role in maintaining homeostasis, which includes regulating body temperature. It acts as a thermostat for the body.
- **Basal Ganglia**: This group of nuclei in the brain is involved in the regulation of voluntary motor control, but it does not have a role in temperature regulation.
- **Cerebellum**: This part of the brain is responsible for coordination and balance, but it does not regulate body temperature.

3. **Determine the Correct Answer**: Based on the functions described:
- The **hypothalamus** is the only option that is directly involved in maintaining the body temperature at approximately 37°C through its homeostatic functions.

4. **Conclusion**: Therefore, the correct answer to the question is **B) Hypothalamus**.
