The uterosacral ligament primarily provides support by attaching the cervix to what structure?

• A. Attaches cervix to sacrum
• B. Attaches cervix to pubic symphysis
• C. Attaches uterus to ovaries
• D. Attaches uterus to ileum

Answer: (A)

The main idea is that this ligament provides posterior pelvic support by anchoring the cervix to a strong posterior bony structure. The uterosacral ligaments extend from the sacrum up to the cervix and posterior vaginal wall. By tethering the cervix to the sacrum, they help keep the uterus in its normal position and resist downward or forward displacement that could lead to prolapse. This posterior attachment contrasts with other potential connections, like to the pubic symphysis or to the ovaries, which are not the primary posterior support for the cervix. The uterosacral attachment to the sacrum is the key feature that stabilizes the cervix within the pelvis.
