Fallopian tube

One of the 2 tubes that extend from the uterus to the ovary. The fallopian tube transports eggs and sperm and is where fertilization takes place. The tube opens into the uterus at one end, and the other end, which is divided into fimbriae (finger-like projections), lies close to the ovary. The tube has muscular walls lined by cells with cilia (hair-like projections). The fimbriae take up the egg after it is expelled from the ovary. The beating cilia and muscular contractions propel the egg towards the uterus. After intercourse, sperm swim up the fallopian tube from the uterus. The lining of the tube and its secretions sustain the egg and sperm, encouraging fertilization, and nourish the egg until it reaches the uterus. Salpingitis is inflammation of the fallopian tube, usually the result of a sexually transmitted bacterial infection, that can lead to infertility. An ectopic pregnancy (development of an embryo outside the uterus) most commonly occurs in the fallopian tube.
