Organization of the Subdiaphragmatic Vagus Nerve and Its Connection with the Celiac Plexus and the Ovaries in the Female Rat

Communication between the ovaries and central nervous system occurs by peripheral innervation through celiac plexus, superior ovarian nerve, plexus nerve. The vagus nerve is involved in regulating ovaries, but neuroanatomical pathway that links them not clear. Adult female rats were used for gross anatomy, acetylcholinesterase histochemistry, immunofluorescence analysis of tyrosine hydroxylase (TH), choline acetyltransferase (ChAT), tryptophan 2 (TPH). results obtained indicate right (RVN) travels parallel caudal to esophagus, where three branches identified. Also, a vagal (RVP) formed microganglia was described, establishing communication with mainly reactive (TH); some serotoninergic cholinergic neurons also found. left (LVN) over bifurcates before its insertion into stomach enters RCG.
