Answer

To solve the question "Which of the following is not a part of the Fallopian tube?", we will analyze the options provided: infundibulum, isthmus, cervix, and ampula.

### Step-by-Step Solution:

1. **Understand the Structure of the Fallopian Tube**:
- The Fallopian tube is divided into several parts: the infundibulum, ampula, isthmus, and fimbriae.
- The infundibulum is the funnel-shaped end of the tube that has finger-like projections called fimbriae, which help in capturing the ovum from the ovary.
- The ampula is the wider section of the tube where fertilization typically occurs.
- The isthmus is the narrowest part of the Fallopian tube that connects to the uterus.

2. **Identify Each Option**:
- **Infundibulum**: This is a part of the Fallopian tube.
- **Isthmus**: This is also a part of the Fallopian tube.
- **Cervix**: This is not a part of the Fallopian tube; it is the lower part of the uterus that opens into the vagina.
- **Ampula**: This is a part of the Fallopian tube.

3. **Conclusion**:
- After analyzing the options, we find that the cervix is the only structure listed that is not a part of the Fallopian tube. Therefore, the answer to the question is **cervix**.

### Final Answer:
The structure that is not a part of the Fallopian tube is **cervix** (Option 3).
