Its cell body is located contralateral to the muscle it innervates, the next anterior neuromere, and it fasciculates with the ISNb nerve branch (Hoang and Chiba, 2001; Kohsaka et al., 2012). During metamorphosis, VL1 muscles in abdominal segments 1 and 2 develop into temporary eclosion muscles, with some remodeling of the corresponding VL1 motor neurons, which become adult persistent 12-Ib motor neurons (Banerjee et al., 2016). The VL1 neurons found in (at least) abdominal neuromeres 2-4 die during metamorphosis (Banerjee et al., 2016). fly_anatomy.ontology VFB:FBbt_00047470 A1-7 MN12-Ib larval A1-7-innervating ISN motor neuron
