It exits the ventral nerve cord via the posterior root of the intersegmental nerve and fasciculates with the ISNb or ISNd intersegmental nerve branches. These neurons have a similar central arborization pattern to the dorsal and lateral 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). abdominal ventral VUM motor neuron larval abdominal intersegmental nerve motor neuron larval posterior intersegmental nerve root of A1-7 larval A1-7-innervating ISN motor neuron larval ventral VUM motor neuron cell body rind of larval abdominal neuromere
