fasciculates with sends synaptic output to cell adult pharyngeal nerve proboscis muscle 3 lateral motor neuron 2021-03-29T15:50:29Z VFB:FBbt_00051185 proboscis motor neuron mn3L fly_anatomy.ontology Motor neuron that innervates lateral fibers of proboscis muscle 3, which flexes the haustellum (McKellar et al., 2020). 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).
