It exits the ventral nerve cord via the segmental nerve and fasciculates with the SNa segmental nerve branches. These neurons have a similar central arborization pattern to the dorsal and ventral VUM neurons of A1-7. They arborize along and dorsal to the dorsal median fascicle and laterally along the dorsal lateral fascicle, invading the next anterior neuromere. In the dorsomedial neuropil, arborizations are sent into at least two (usually three) anterior neuromeres and the adjacent posterior neuromere (Selcho et al., 2012).
