Which part of brain is supposed to be damaged if in an accident , a person lost control of water balance, hunger and body temp. :

Options

A. Cerebellum
B. Hypothalamus
C. Medula oblongata
D. Corpora quadrigemina

Answer

To determine which part of the brain is damaged when a person loses control of water balance, hunger, and body temperature after an accident, we can analyze the functions of the different brain regions mentioned in the options.

### Step-by-Step Solution:

1. **Identify the Symptoms**: The symptoms mentioned are loss of control over water balance, hunger, and body temperature. These functions are crucial for maintaining homeostasis in the body.

2. **Analyze the Options**:
- **Cerebellum**: This part of the brain is primarily responsible for coordination and balance. Damage here would affect motor control and coordination, but not hunger, thirst, or temperature regulation.
- **Hypothalamus**: The hypothalamus is a critical control center for many autonomic functions, including hunger, thirst, and body temperature regulation. It plays a significant role in maintaining homeostasis.
- **Medulla Oblongata**: This area controls vital functions such as breathing and heart rate. Damage here would lead to respiratory issues but not directly affect hunger or thirst.
- **Corpora Quadrigemina**: This part is involved in visual and auditory reflexes. Damage would lead to problems with sight and hearing, not hunger or temperature control.

3. **Conclusion**: Given that the hypothalamus regulates hunger, thirst, and body temperature, if a person has lost control over these functions, it indicates that the hypothalamus is likely the part of the brain that has been damaged.

### Final Answer:
The part of the brain that is supposed to be damaged is the **Hypothalamus**.
