Which ligament extends from the upper cervix to the lateral margins of the sacrum, firmly supporting the cervix?

• A. Ovarian ligament
• B. Round ligament
• C. Suspensory ligament
• D. Uterosacral ligament

Answer: (D)

The main concept here is how the uterus is anchored and supported within the pelvis. The ligament that provides strong posterior support for the cervix by connecting it to the sacrum is the uterosacral ligament. It originates from the cervix and upper vagina and extends backward to attach to the sacrum, helping hold the uterus in its proper position and resisting downward movement that could lead to prolapse.

Other ligaments listed serve different connections: the ovarian ligament links the ovary to the uterus, the round ligament runs from the uterus toward the labia majora to help with anteversion, and the suspensory (infundibulopelvic) ligament anchors the ovary to the lateral pelvic wall and carries vessels. None of these provide the same direct cervix-to-sacrum posterior support that the uterosacral ligaments do.
