General Information
Term proboscis muscle 9 ID (Ontology) FBbt:00058797 (Fly Anatomy)
Definition Muscle of the proboscis that has its origin in the gena, in the ventral wall of the head, and its insertion site on the apodeme of the rostrum (Rajashekhar and Singh, 1994; McKellar et al., 2020). Its contraction results in rotation of the apodeme and the rostrum, causing the proboscis to extend (McKellar et al., 2020). It is synapsed by the proboscis muscle 9 motor neuron (Gordon and Scott, 2009; McKellar et al., 2020).[ FlyBase:FBrf0007735 FlyBase:FBrf0074226 FlyBase:FBrf0193310 FlyBase:FBrf0206709 FlyBase:FBrf0246028 ]
