A man is admitted toa hospital. He is suffering from an abnormally low body temperature, loss of appetitie and extreme thirst. His brains scan would probably show a tumor in

Options

A. Pons
B. Cerebellum
C. Medulla oblongata
D. Hypothalamus

Answer

**Step-by-Step Solution:**

1. **Identify the Symptoms**: The man exhibits three primary symptoms: abnormally low body temperature, loss of appetite, and extreme thirst.

2. **Understand the Role of the Hypothalamus**: The hypothalamus is a crucial part of the brain that regulates various bodily functions, including body temperature, hunger, and thirst. It is often referred to as the "master of the master gland" because it controls the pituitary gland, which in turn regulates many other hormones in the body.

3. **Relate Symptoms to Brain Function**: Given the symptoms, we can deduce that the hypothalamus is likely affected. A tumor in this area could disrupt its normal functions, leading to the observed symptoms:
- **Low Body Temperature**: The hypothalamus regulates thermoregulation. A tumor could impair its ability to maintain normal body temperature.
- **Loss of Appetite**: The hypothalamus also controls hunger signals. A tumor could interfere with these signals, leading to a decreased appetite.
- **Extreme Thirst**: The thirst center in the hypothalamus regulates fluid balance. A tumor could cause an imbalance, resulting in extreme thirst.

4. **Conclusion**: Based on the symptoms and the functions of the hypothalamus, it is likely that the man has a tumor in the hypothalamus region of the brain.

**Final Answer**: The man's brain scan would probably show a tumor in the hypothalamus.
