Term paraesophageal ganglion ID (Ontology) FBbt:00002635 (Fly Anatomy)
Definition Small ganglion of the embryonic/larval stomatogastric nervous system located on the right hand side of the larva, between the two brain hemispheres, behind the supraesophageal commissure. It is elongated, less compact than the hypoesophageal ganglion and occupies a more ventral position, closely attached to the esophageal wall. It contains 10-12 neurons.[ FlyBase:FBrf0078614 FlyBase:FBrf0089570 ]
