General Information
Term tergopleural muscle ID (Ontology) FBbt:00058907 (Fly Anatomy)
Definition Indirect flight muscle that originates broadly over the dorsal episternum and inserts via a thick tendon on the meso-scutum (Dickinson and Tu, 1997). This muscle is innervated by the dorsal and ventral tp motor neurons.[ FlyBase:FBrf0007735 FlyBase:FBrf0064793 FlyBase:FBrf0074636 FlyBase:FBrf0098527 FlyBase:FBrf0192609 FlyBase:FBrf0193310 ]
Also Known As "3rd & 4th basalar muscle" ; "basalar muscle 52" ; "direct flight muscle 52" (for all, see Synonyms field below)
Comment Classified as indirect in Dickinson and Tu (1997), as these muscles do not connect to a wing sclerite, but they note that the muscles do insert within the hinge region and could affect hinge mechanics.
