larval A1-7-innervating VO1 motor neuron [FBbt_00002223]

RP4 neuron that innervates the internal ventral oblique muscle 1 (VO1; muscle 30) of segments A1-7. 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). The VO1 neuron found in the metathoracic neuromere switches muscle targets during metamorphosis to become adult persistent motor neuron 30-Ib (Banerjee et al., 2016). The VO1 cells of (at least) abdominal neuromeres 1-3 die during metamorphosis (Banerjee et al., 2016).
