Uterosacral ligament


The uterosacral ligaments are major ligaments of uterus that extend posterior-ward from the cervix to attach onto the sacrum.''''''

Structure

Microanatomy/histology

The uterosacral ligaments consist of fibrous connective tissue, and smooth muscle tissue.''''''

Relations

The uterosacral ligaments pass inferior to the peritoneum. They embrace the rectouterine pouch, and rectum. The pelvic splanchnic nerves run on top of the ligament.

Function

The uterosacral ligaments pull the cervix posterior-ward, counteracting the anterior-ward pull exerted by the round ligament of uterus upon the fundus of the uterus, thus maintaining anteversion of the body of the uterus.''''''

Clinical significance

The uterosacral ligaments may be palpated during a rectal examination, but not during pelvic examination.''''''
