Studies on the muscular structure of the human uterus. II. Fasciculi cervicoangulares: vestigial or functional remnant of the mesonephric duct?
Two muscle bundles, the fasciculi cervicoangulares (FCAs), are present at the lateral aspect of the human uterus bridging cervix and fundus uteri. Epithelial remnants within this muscle bundle are morphologically identical with mesonephric duct remnants. It is postulated that the longitudinal muscle coat of the mesonephric duct may develop into the two FCAs and that these bundles may serve as a system for conduction or coordination of muscle contractions in the adult uterus.
