General Information
Term adult dorsal tracheal branch ID (Ontology) FBbt:00003051 (Fly Anatomy)
Definition Adult trachea that branches dorsally from the dorsal trunk. It tracheates the dorsal epidermis and dorsal vessel. Each dorsal branch connects the left and right dorsal trunks of the same tracheal metamere via the dorsal anastomosis. In the thorax, the dorsal branches connect the parenteric air sacs, which correspond to the enlarged dorsal trunks.[ FlyBase:FBrf0011558 FlyBase:FBrf0064787 FlyBase:FBrf0186027 ]
Also Known As"dorsal anastomose" ; "transverse dorsal commissure"
