General Information
Term proboscis muscle 9 motor neuron ID (Ontology) FBbt:00111298 (Fly Anatomy)
Definition Motor neuron that innervates proboscis muscle 9, which extends the rostrum (Gordon and Scott, 2009; McKellar et al., 2020). Its soma is found in a dorsal part of the cell body rind of the subesophageal zone (Gordon and Scott, 2009; McKellar et al., 2020). It arborizes broadly in the ventral subesophageal zone, mostly ipsilaterally, and exits the brain via the pharyngeal nerve (Gordon and Scott, 2009; McKellar et al., 2020). This neuron is required for normal proboscis extension (Gordon and Scott, 2009).[ FlyBase:FBrf0206709 FlyBase:FBrf0246028 ]
