Question

1. Explain how the migration of an ovum through a fallopian tube is accomplished.

Answer 1

Migration of ovum through fallopian tube

The ovum that is produced by ovary gas to be transported through the fallopian tube to reach the site of fertilization. In the process the expulsion of ovum from ovary occur and it will cause the specific movement of the ovum into the distal part of the fallopian tube . The fimbria is the one that will allow the movement of ovum from the ovary to the fallopian duct . And the egg will reach the ampulla where the fertilization process occur . It stays in the fallopian tube fkr 5 days as it move after fertilized and then reach the uterine cavity.

The ciliated and non ciliated cells in the fallopian tube plays a major role in the movements. It is regulated by the hormone like estrogen and progesterone that helps in changing the lining of fallopian tube for movement of ovum . The first four days of follicular phase the specific propulsive forces will operate throughout the fallopian canal in the direction specific to the uterus. In the mid-follicular phase that is from day 8 the ampulla has alternating propulsive forces towards as well as away from the uterus. During ovulation phase the ipsilateral transport to the ovary increases causing the specific increase in diameter of Folicle.

It moves in the order as it moves to infundibulum with help of fimbriae into tee ambulla where fertilization occur and the development of zygote occur and further movement into istumus and then to uterus
