Description: The uterine (Fallopian) tubes extend laterally from both upper lateral regions of the uterus. Each has four regions (medial to lateral): the interstitial or intramural portion, the isthmic portion, the ampulla, and the infundibulum or fimbria. The lateral regions, the ampulla and  "fimbria" resembling the shape of a trumpet, swing freely on the mesosalpinx, usually hanging adjacent to the ovary. The uterine tube is supplied by the anastomosing branches of the uterine and ovarian vessels.
