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 fasciculating with the ISNb nerve branch. Its soma is located in the segment anterior to the muscle it innervates (Landgraf et al., 1997). These neurons (at least in T3-A3 neuromeres) die during metamorphosis (Banerjee et al., 2016). fly_anatomy.ontology RP3 motor neuron FBbt:00110248 VFB:FBbt_00002215 MN-VL3/4 larval abdominal intersegmental nerve motor neuron larval intersegmental nerve branch ISNb of A1-7 lineage NB3-1 primary motor neuron type Ib motor neuron larval internal muscle motor neuron larval anterior intersegmental nerve root of A1-7 larval lateral A1-7-innervating ISN motor neuron
