Question

Which of the following represents the correct pathway of the egg after leaving the ovary and entering the uterine tube?

Answer 1

Answer: Infundibulum, ampulla, isthmus, uterus.

Explanation:

• The ovary produces the egg and, it releases one unfertilized egg every month.

• The egg then travels through the fallopian tube to the uterus.

• The fallopian tube consists of three parts:

1. Infundibulum- it is the most distal portion of the fallopian tube which receives the egg coming out of the ovary.

2. Ampulla- This is the next portion of the fallopian tube which is ciliated and is the site of fertilisation of the egg.

3. Isthmus- it is also a ciliated region which controls the transport of both sperm and the embryo.

• Finally, after passing through the isthmus the fertilized egg reaches the uterus where implantation takes place.

• So the journey of the egg from the ovary to uterus follows the pathway, ovary---> infundibulum--->ampulla--->isthmus--->uterus.
