FBbt:00110240 fly_anatomy.ontology 3-2Mar A1-7 MN-DO4 VFB:FBbt_00110240 3-2M Larval motor neuron that innervates the internal dorsal oblique muscle 4 (DO4) in larval abdominal segments A1 to A7. It develops from neuroblast NB3-2 (Landgraf et al., 1997). Its dendritic arborization occupies the lateral domain of the ventral nerve cord neuropil. It exits the ventral nerve cord via the anterior root of the intersegmental nerve and innervates the DO4 muscle with type Ib boutons (Landgraf et al., 1997; Hoang and Chiba, 2001). These neurons (at least in A1 to A4) die during metamorphosis (Banerjee et al., 2016). Its soma is located in the segment anterior to the muscle innervated (Kohsaka et al., 2012). A1-7 MN19-Ib
