Which of the following is NOT a part of the broad ligament?

• A. Mesovarium
• B. Mesometrium
• C. Round ligament
• D. Mesosalpinx

Answer: (C)

The broad ligament is a peritoneal sheet that drapes over the uterus and uterine adnexa, forming three extending portions: the mesometrium (the part attached to the body of the uterus and lateral wall), the mesovarium (the portion that attaches the ovary to the broad ligament), and the mesosalpinx (the portion that encloses and supports the fallopian tube). Among the structures listed, the round ligament is not a part of this peritoneal double layer. It is a fibromuscular cord derived from the gubernaculum that runs from the uterus to the labia majora through the inguinal canal, helping maintain uterine anteversion. The other three are true components of the broad ligament, while the round ligament lies outside of its peritoneal reflections.
