Which of the following is not a component of Fallopian tube?

The correct answer is Uterine fundus.

Step-by-step Explanation:

1. Anatomy of the Fallopian Tube: The Fallopian tubes (also known as oviducts or uterine tubes) are paired female reproductive organs that connect the ovaries to the uterus. Each tube is anatomically divided into four main regions, starting from the ovary side and moving towards the uterus:
- Infundibulum: The funnel-shaped outer end of the tube closest to the ovary. It features finger-like projections called fimbriae that help catch the ovulated egg.
- Ampulla: The wide, thin-walled, middle section of the Fallopian tube. This is the most common site for fertilization of the egg by sperm.
- Isthmus: The narrow, thick-walled section that connects the ampulla to the uterine wall.
- Uterine/Intramural part: The segment of the tube that passes through the muscular wall of the uterus.

2. Understanding the Uterine Fundus: The uterine fundus is the dome-shaped upper portion of the uterus itself, situated above the entry points of the Fallopian tubes. While it is anatomically close to the tubes, it is a component of the uterus, not the Fallopian tube.

3. Conclusion: Among the options provided, the isthmus, infundibulum, and ampulla are all parts of the Fallopian tube, whereas the uterine fundus is a part of the uterus. Therefore, the uterine fundus is not a component of the Fallopian tube.
