• A. Uterus
• B. Vagina
• C. Ovary
• D. Cervix

Answer: (A)

The uterus is the muscular organ described. Its body and fundus are covered by peritoneum, but the peritoneal covering ends where the cervix begins—below the anterior cervical os—so the portion of the uterus that lies below that level isn’t covered by peritoneum. The uterus is held in place by the pelvic floor muscles, notably the levator ani, and by the main supportive ligaments: the cardinal (transverse cervical) ligaments extending to the lateral pelvic walls and the uterosacral ligaments anchoring to the sacrum. This combination of muscular wall, limited peritoneal covering, and these supports keeps the uterus properly positioned in the pelvis.
