Which of the following is not a component of Fallopian tube?
- Uterine fundus
- Isthmus
- Infundibulum
- Ampulla
The Correct Option is A
Approach Solution - 1
Step 1: Understanding the Components of the Fallopian Tube:
The Fallopian tubes are a pair of tubes connecting the ovaries to the uterus, and they play a critical role in fertilization. They have several distinct parts:
- Infundibulum: This is the funnel-shaped opening of the Fallopian tube near the ovary. It has finger-like projections called fimbriae that help capture the egg released from the ovary.
- Ampulla: This is the widest section of the Fallopian tube where fertilization typically occurs. It is located between the infundibulum and isthmus.
- Isthmus: The isthmus is a narrow part of the Fallopian tube that connects the ampulla to the uterus. It transports the fertilized egg to the uterus for implantation.
Step 2: Uterine Fundus:
The uterine fundus is the upper part of the uterus, not a part of the Fallopian tube. It is the region where a fertilized egg may implant if the fertilization occurs successfully. The uterine fundus is not involved in the transport of eggs or sperm and does not form part of the Fallopian tube system.
Step 3: Conclusion:
The correct answer is Option 1, the uterine fundus, because it is not a component of the Fallopian tube.
Answer: The correct answer is Option 1: Uterine fundus.
Approach Solution -2
The Fallopian tube is an essential part of the female reproductive system, responsible for transporting eggs from the ovaries to the uterus. It consists of four main components:
- Infundibulum: The funnel-shaped opening near the ovary, which captures the released egg.
- Ampulla: The widest section where fertilization often occurs.
- Isthmus: The narrow part of the tube that connects to the uterus.
- Uterine part (or Interstitial part): The section that passes into the uterine wall.
Among the options provided, the Uterine fundus is not a component of the Fallopian tube. Instead, it refers to the upper part of the uterus itself.
