Mesometrium The mesometrium is the part of the broad ligament of the uterus that attaches the body of the uterus to the pelvic wall. The ureters pass through the base of the mesometrium as they travel to reach the bladder. See Netter Plate 346 for a picture of this relationship. The mesovarium is the part of broad ligament that forms a shelf-like fold supporting the ovary. The suspensory ligament of the ovary, which conveys the ovarian vessels, lymphatics, and nerves to and from the ovary, constitutes the lateral part of the mesovarium of the broad ligament. The mesosalpinx is the part of broad ligament that supports the uterine tube. Finally, the round ligament of the uterus is a connective tissue band that attaches to the inner aspect of the labium majus and the uterus. It lies in the mesometrium, and it is continuous with the ovarian ligament.
