Motor neuron that innervates the muscles of larval abdominal segments A1-7 and which fasciculates with the intersegmental nerve. Except for RP2 (dorsal motor neuron) their somas are located in the next anterior segment to the muscles they innervate (Zarin and Labrador, 2019). The dendritic domain of the motor neuron is located anteriorly to the dendritic domain of the motorneurons that innervate external muscles.
