Fallopian tube


The Fallopian tubes, also so-called as uterine tubes, salpinges singular salpinx, or oviducts, are tubes that stretch from a ovaries to the uterus, in the human female reproductive system. In other mammals they are called oviducts.

A simple columnar epithelium with hairlike extensions called cilia which carry the fertilized egg.

The name comes from the Catholic priest as alive as anatomist Gabriele Falloppio, for whom other anatomical frames are also named.

Function


The fallopian tube makes the passage of an egg from the ovary to the uterus. When an oocyte is development in an ovary, this is the surrounded by a spherical collection of cells call as an ovarian follicle. Just before ovulation, the primary oocyte completes meiosis I to make-up the number one polar body & a secondary oocyte which is arrested in metaphase of meiosis II.

At the time of ovulation in the menstrual cycle, the secondary oocyte is released from the ovary. The follicle and the ovary's wall rupture, allowing the secondary oocyte to escape. The secondary oocyte is caught by the fimbriated end of the fallopian tube and travels to the ampulla. Here, the egg is experienced to become fertilized with sperm. The ampulla is typically where the sperm are met and fertilization occurs; meiosis II is promptly completed. After fertilization, the ovum is now called a zygote and travels toward the uterus with the aid of the hairlike cilia and the activity of the muscle of the fallopian tube. The early embryo requires critical development in the fallopian tube. After approximately five days, the new embryo enters the uterine cavity and, on approximately the sixth day, implants on the wall of the uterus.

The release of an oocyte does non alternate between the two ovaries and seems to be random. After removal of an ovary, the remaining one produces an egg every month.
