The primary neurites of OA-VUM neurons join one of the three median tracts along the anterioposterior axis and mainly innervate the periesophageal region. These neurites follow the tracts toward the posterior ventral area of the esophagus foramen where they symmetrically branch out to innervate the cerebral ganglion and subesophageal zone and in some cases the ventral nerve cord. Two main subtypes can be identified: OA-VUMa and OA-VUMd (Busch et al., 2009; Certel et al., 2010). adult subesophageal zone
