Uterine tube

Uterine tube

The uterine tube, also known as the Fallopian tube, is a part of the female reproductive system. It is the structure that transports the egg from the ovary to the uterus. The uterine tube is essential for fertilization, as it is the site where the sperm meets the egg.

Anatomy

The uterine tube is a tubular structure that extends from the uterus to the ovary. It is divided into four parts: the infundibulum, the ampulla, the isthmus, and the intramural part. The infundibulum is the funnel-shaped end of the tube that is close to the ovary. The ampulla is the longest part of the tube and is the site of fertilization. The isthmus is the narrow part of the tube that connects to the uterus. The intramural part is the part of the tube that is within the wall of the uterus.

Function

The primary function of the uterine tube is to transport the egg from the ovary to the uterus. This is facilitated by the cilia, tiny hair-like structures that line the inside of the tube. The cilia beat in a coordinated manner to move the egg along the tube. The uterine tube is also the site of fertilization. After ovulation, the egg is picked up by the infundibulum and travels down the tube. If sperm are present, fertilization can occur in the ampulla.

Clinical significance

Diseases of the uterine tube can lead to infertility, ectopic pregnancy, and pelvic inflammatory disease. Blockage of the tube can prevent the egg from reaching the uterus, leading to infertility. An ectopic pregnancy occurs when a fertilized egg implants in the tube instead of the uterus. Pelvic inflammatory disease is an infection of the female reproductive organs, including the uterine tube.
