Which is mis-matched?

Options

A. Cerebrum-memory
B. Medulla oblongata-temperature regulation
C. Cerebellum - equilibrium
D. Olfactory lobes -smell

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks us to identify which pair of brain structures and their functions is mismatched. We need to analyze each option provided.

2. **Analyzing the First Option**:
- **Pair**: Cerebrum and Memory
- **Function**: The cerebrum is indeed involved in various functions including coordination of movement, touch, vision, hearing, and memory.
- **Conclusion**: This pair is correctly matched.

3. **Analyzing the Second Option**:
- **Pair**: Medulla Oblongata and Temperature Regulation
- **Function**: The medulla oblongata is primarily responsible for autonomic functions such as respiration and heart rate. Temperature regulation is actually managed by the hypothalamus.
- **Conclusion**: This pair is mismatched.

4. **Analyzing the Third Option**:
- **Pair**: Cerebellum and Equilibrium
- **Function**: The cerebellum is responsible for coordination and balance, which includes maintaining equilibrium.
- **Conclusion**: This pair is correctly matched.

5. **Analyzing the Fourth Option**:
- **Pair**: Olfactory Lobes and Smell
- **Function**: The olfactory lobes are responsible for the sense of smell.
- **Conclusion**: This pair is correctly matched.

6. **Final Conclusion**: Based on the analysis, the mismatched pair is the second option: Medulla Oblongata and Temperature Regulation.

**Final Answer**: The mismatched pair is Medulla Oblongata and Temperature Regulation.
