It is located in a relatively ventral (distal) position compared to other cibarial muscles, with which it functions in cibarial pumping. It is synapsed by the proboscis muscle 12 dorsal motor neuron (McKellar et al., 2020). proboscis muscle 11-3 proboscis muscle 12-2 proboscis muscle m12D FBbt:00058800 rostrum muscle proboscis muscle 12 dorsal motor neuron
