larval A1-7-innervating ventral VUM motor neuron [FBbt_00002247]

Neuromodulatory motor neuron that innervates the internal ventral oblique (VO1,2,4,5,6) and ventral longitudinal (VL1,2) muscles of larval abdominal segments A1 to A7 (except VO6, which is only present in A2-7) via type II boutons (Hoang and Chiba, 2001). 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).
