General Information
Term direct flight muscle ID (Ontology) FBbt:00058900 (Fly Anatomy)
Definition Relatively small muscle that inserts directly on a sclerite of the wing hinge to allow for the fine control of wing positioning for behaviors such as flight, grooming or courtship (Dickinson and Tu, 1997). There are thirteen of these muscles on each side (Dickinson and Tu, 1997). It is derived from a direct flight muscle precursor cell of the wing disc (Kozopas and Nusse, 2002).[ FlyBase:FBrf0007735 FlyBase:FBrf0064793 FlyBase:FBrf0098527 FlyBase:FBrf0144806 ]
Also Known As "direct flight control muscle" ; "direct wing muscle" ; "flight steering muscle"
