Its dendritic arborization occupies the intermediate domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the LL1 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). Its soma is found in the segment anterior to the muscle it innervates (Kohsaka et al., 2012). VFB:FBbt_00110235 fly_anatomy.ontology A1-7 U5 motor neuron
