Fallopian tube. The Fallopian tubes, also known as, uterine tubes, and salpinges (singular salpinx), are two very fine tubes lined with ciliated epithelia, leading from the ovaries of female mammals into the uterus, via the uterotubal junction. In non-mammalian vertebrates, the equivalent structures are called oviducts.
