Its soma is found in a dorsal 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 pharyngeal nerve (McKellar et al., 2020). proboscis motor neuron mn5 haustellum muscle motor neuron pharynx muscle motor neuron
