What are the round ligaments?

The round ligaments are specialized structures that help support the uterus and maintain its position within the pelvic cavity. They extend from the uterus to the lateral pelvic walls and play a crucial role in providing stability during pregnancy as the uterus grows and shifts in position.

While they do assist in supporting the uterus, their classification as abdominal supporting ligaments highlights their broader function in the anatomy of the female reproductive system, where they contribute to the overall integrity and support of the pelvic floor and associated organs. This makes them distinctly different from other structures listed in the question, such as nerves or muscles, which serve different functions altogether.
