Its soma is found in a ventral part of the cell body rind of the subesophageal zone (McKellar et al., 2020). It arborizes in the ventral subesophageal zone and travels to the proboscis via the labial nerve (McKellar et al., 2020). proboscis motor neuron mn6 FlyWire CB0858 mapped to MN6 in Shiu et al.
