Correct Answer � D Explanation |
 |
Option D: Round ligament
- Round ligament:
- Derivative of gubernaculum.
- Attaches the utero-tubal junction (uterine horn) to the labia majora.
- Responsible for maintaining the anteverted and anteflexed position of the uterus.
- Normally, the position of the uterus is anteverted and anteflexed.
- Anteversion of the uterus is described as the long axis of the uterus being curved forward about the long axis of the vagina.
- The angle of anteversion is 90°.
- Anteflexion of the uterus is described as the cervix's long axis, and the uterus' long axis both curved forward at the level of the internal os. The angle of anteflexion is 125 -170°.
Option A: Cardinal ligament
- The cardinal ligament attaches the lateral side of the vagina and cervix to the lateral pelvic wall, which provides support to the vagina and cervix. It does not take part in maintaining the anteversion of the uterus
Option B: Uterosacral ligament
- The uterosacral ligament does not maintain the anteversion of the uterus; rather, It keeps the uterus and cervix in the pelvis and helps prevent uterine prolapse.
Option C: Ovarian ligament
- The ovarian ligament attaches the ovary to the side of the uterus, lying within the broad ligament. It serves as a fibrous band of tissue connecting the ovary inferiorly to the uterus, joining the uterus just below the origin of the fallopian tubes.
