General Information
Term embryonic/larval ganglionic tracheal branch ID (Ontology) FBbt:00000325 (Fly Anatomy)
Definition Embryonic/larval trachea that branches from the lateral trunk and which tracheates the ventral nerve cord. The three most anterior ganglionic branches (GB0-GB2) anastomose mid-ventrally with the branch from the opposite hemisphere, forming a ventral anastomose. In the larva, the last two pairs of ventral ganglionic branches terminate without tracheating the posterior ventral nerve cord.[ FlyBase:FBrf0011558 FlyBase:FBrf0064787 ]
Also Known As "i branch" ; "larval ganglionic branch" ; "larval ganglionic trachea" (for all, see Synonyms field below)
