Question

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

• A. Uterine fundus
• B. Isthmus
• C. Infundibulum
• D. Ampulla

Answer 1

The Correct Option is A

Step 1: Fallopian Tube Structure:

The Fallopian tubes, connecting ovaries to the uterus, are vital for fertilization. Their components include:

• Infundibulum: Funnel-shaped, near the ovary, with fimbriae to capture released eggs.
• Ampulla: Widest section, between infundibulum and isthmus, where fertilization usually happens.
• Isthmus: Narrow section connecting the ampulla to the uterus, transporting fertilized eggs for implantation.

Step 2: Uterine Fundus Description:

The uterine fundus is the upper portion of the uterus. It is not part of the Fallopian tubes. This region is where a fertilized egg might implant after successful fertilization. The uterine fundus does not participate in egg or sperm transport or the Fallopian tube system.

Step 3: Determination:

The correct selection is Option 1, the uterine fundus, due to its exclusion from the Fallopian tube's structure.

Answer: The correct answer is Option 1: Uterine fundus.
