General Information
Term radial vein ID (Ontology) FBbt:00047863 (Fly Anatomy)
Definition Proximal region of the L1, L2 and L3 wing veins prior to branching. It can be further subdivided into proximal, medial and distal parts. This vein contains several fields of sensilla.[ FlyBase:FBrf0038304 FlyBase:FBrf0040724 FlyBase:FBrf0202743 ]
Also Known As "radius"
Comment Sometimes referred to as the proximal radius, where the term radius is used to include the full L3 vein (e.g. Bryant, 1975 - FBrf0027793).
