Options

A. controlling body temperature
B. urge for drinking
C. urge for eating
D. thinking, reasoning

Answer

To determine which function is not related to the hypothalamus, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding the Hypothalamus Functions:**
The hypothalamus is a crucial part of the brain that regulates various autonomic functions. It plays a significant role in maintaining homeostasis, including temperature regulation, thirst, hunger, and circadian rhythms.

2. **Analyzing Option A: Controlling Body Temperature**
- The hypothalamus is responsible for thermoregulation, which is the process of maintaining an optimal body temperature.
- Therefore, this option is related to the hypothalamus.

3. **Analyzing Option B: Urge for Drinking**
- The hypothalamus also regulates thirst and the urge to drink, responding to changes in body hydration levels.
- Thus, this option is also related to the hypothalamus.

4. **Analyzing Option C: Urge of Eating (Hunger)**
- The lateral hypothalamus specifically is involved in the regulation of hunger and the urge to eat.
- Hence, this option is related to the hypothalamus as well.

5. **Analyzing Option D: Thinking and Reasoning**
- Thinking and reasoning are functions primarily associated with the cerebrum, not the hypothalamus.
- Therefore, this option is the one that is NOT related to the hypothalamus.

### Conclusion:
The correct answer is **Option D: Thinking and Reasoning**, as these functions are controlled by the cerebrum, not the hypothalamus.
