Which of the following features is not related with pons?

Options

A. It forms floor or brain stem
B. It serves as neural link between different parts of brain
C. It can moderates the functions of respiratory rhythm centre
D. It has a chemosensitive area for respiratory regulation

Answer

### Step-by-Step Solution:

1. **Understanding the Pons**:
- The pons is a part of the brainstem located above the medulla oblongata. It acts as a relay station for signals between different parts of the brain.

2. **Functions of the Pons**:
- The pons plays a crucial role in regulating various functions such as sleep, respiration, hearing, and taste. It serves as a control center for these signals.

3. **Analyzing the Options**:
- The question asks for a feature that is **not** related to the pons. We need to evaluate each option provided.

4. **Option Evaluation**:
- **Option 1**: "It forms the floor of the brainstem."
- This is true as the pons is indeed part of the brainstem.
- **Option 2**: "It serves as a neural link between different parts of the brain."
- This is also true since the pons connects various brain regions.
- **Option 3**: "It can moderate the function of respiratory rhythm centers."
- This is partially true, but the pons does not fully control the respiratory centers.
- **Option 4**: "It has a chemosensitive area for respiratory regulation."
- This is false because the chemosensitive area is located in the medulla, not in the pons.

5. **Conclusion**:
- The feature that is not related to the pons is the last option: "It has a chemosensitive area for respiratory regulation."

### Final Answer:
The feature that is not related to the pons is: **"It has a chemosensitive area for respiratory regulation."**
