General Information
Term larval A1-7-innervating V motor neuron ID (Ontology) FBbt:00110302 (Fly Anatomy)
Definition Neuromodulatory motor neuron that develops from the neuroblast 5-2 and innervates the ventral longitudinal muscle 1 (Landgraf et al., 1997). It fasciculates with the ISNb intersegmental nerve branch, innervating VL1 via type III boutons (Hoang and Chiba, 2001; Zarin et al., 2019). It soma is one segment anterior to the muscle it innervates, in the contralateral hemineuromere (Landgraf et al., 1997).[ FlyBase:FBrf0099344 FlyBase:FBrf0112030 FlyBase:FBrf0132289 FlyBase:FBrf0160715 FlyBase:FBrf0167986 FlyBase:FBrf0174847 FlyBase:FBrf0208790 FlyBase:FBrf0244727 ]
Also Known As "A1-7 AC" ; "A1-7 MN-V" ; "A1-7 MN12-III" (for all, see Synonyms field below)
