FallopiantubesThe fallopian tubes, also called oviducts and uterine tubes, are attached to the uterus at its upper,outer angles. They lie between the folds of the broad Ligaments and extend upward and outwardtoward the pelvic sidewalls and then curve downward and backward.The walls of the tubes are composed of the same three tissue layers as the uterine corpus.• A ciliated mucous lining of epithelial tissue. (The cilia propel the ovum from theovary to the uterus.)• Smooth muscle• Serosa (or external peritoneal covering)At the distal end, each tube expands into a funnel-like portion (the infundibulum) which resemblesa fringe or is "fimbriated." Here the mucous lining of the tubes is directly continuous with theperitoneum. The fallopian tubes serve as ducts for the ova produced by the ovaries. Fertilization(union of a spermatozoon and an ovum) normally occurs in the fallopian tubes. Tumors of thefallopian tubes are extremely rare.RegionalLymph NodesThe regional lymph nodes for the fallopian tubes are:Pelvic lymph nodesCommon iliacInternal lilac (hypogastric, including obturator)External iliacLateral sacralAortic (para-, peri-, lateral)Inguinal282
