The correct answer is: Mesosalpinx

The mesosalpinx is the part of broad ligament that supports the uterine tube. The mesosalpinx extends inferiorly to meet the root of the mesovarium; it attaches the uterine tube to the mesometrium. The mesometrium is the part of the broad ligament below the junction of the mesosalpinx and the mesovarium; it attaches the body of the uterus to the pelvic wall. The mesovarium is the part of broad ligament that forms a shelf-like fold supporting the ovary--it attaches the ovary to the mesometrium and mesosalpinx. 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 is found in the broad ligament, and it traverses the inguinal canal.
