attached to receives synaptic input from neuron gena apodeme of rostrum proboscis muscle 9 2022-07-05T13:30:44Z cibarial muscle 9 lateral pharyngeal muscle 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). protractor of fulcrum protractor of rostrum proboscis muscle m9 rostral protractor retractor of fulcrum rostrum protractor muscle fly_anatomy.ontology FBbt:00058797 rostrum muscle proboscis muscle 9 motor neuron
