innervates continuous with common oviduct circular muscle cell adult abdominal nerve trunk peritoneal sheath muscle cell adult abdominal nerve to the ovary 2009-04-03T11:51:41Z FBbt:00007336 VFB:FBbt_00007336 Paired nerve that branches from the abdominal nerve trunk and projects to the junction of the ovaries and the lateral oviduct where it branches repeatedly. Some branches radiate anteriorly across the peritoneal sheath, on which they terminate, mainly in the anterior two thirds of the ovary. Varicosities occur along these branches as well as at their ends. These branches do not penetrate the peritoneal sheath. Other branches innervate the lateral oviduct and the upper portion of the common oviduct. Two types of branches innervate the common oviduct - wandering fibers similar to those on the peritoneal sheath, and branches running circularly, parallel to the underlying myofibers. fly_anatomy.ontology AbNvOv adult abdominal nerve female-specific anatomical entity
