General Information
Term	larval A1-7-innervating lateral VUM motor neuron	ID (Ontology)	FBbt:00002255 (Fly Anatomy)
Definition	Neuromodulatory motor neuron that innervates the lateral transverse (LT1,2,3,4) muscles, as well as the segment border muscle and lateral oblique muscle 1 of larval abdominal segments A1 to A7 via type II boutons (Hoang and Chiba, 2001). 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).[ FlyBase:FBrf0099344 FlyBase:FBrf0112030 FlyBase:FBrf0132289 FlyBase:FBrf0160715 FlyBase:FBrf0167986 FlyBase:FBrf0174847 FlyBase:FBrf0208790 FlyBase:FBrf0219406 ]
Also Known As	"A1-7 lateral MN-VUM" ; "A1-7 MNSNa-II" ; "abdominal lateral VUM motor neuron"
Comment	In A2-7, these neurons might also synapse to muscles 26 (VA1), 27 (VA2) and 29 (VA3) (Selcho et al., 2012).
