Which part of the fallopian tube is closest to the ovary?

Options

A. Infundibulum
B. Ampulla
C. Isthmus
D. Cervix

Answer

To answer the question "Which part of the fallopian tube is closest to the ovary?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Fallopian Tube**:
- The fallopian tube is divided into four main parts:
- Fimbriae
- Infundibulum
- Ampulla
- Isthmus

2. **Identify the Location of Each Part**:
- **Fimbriae**: These are finger-like projections at the end of the fallopian tube that are closest to the ovary.
- **Infundibulum**: This is the funnel-shaped part that follows the fimbriae.
- **Ampulla**: This is the wider section of the tube that comes after the infundibulum.
- **Isthmus**: This is the narrowest part of the fallopian tube, located closest to the uterus.

3. **Determine the Closest Part to the Ovary**:
- Since the fimbriae are the finger-like projections that directly interact with the ovary to catch the released ovum during ovulation, they are the closest structure to the ovary.
- The infundibulum is also close, but the fimbriae are the most proximal part of the fallopian tube to the ovary.

4. **Conclusion**:
- The part of the fallopian tube that is closest to the ovary is the **Fimbriae**.

### Final Answer:
The closest part of the fallopian tube to the ovary is the **Fimbriae**.
