General Information
Term cerebral tracheal branch ID (Ontology) FBbt:00000395 (Fly Anatomy)
Definition Anteriorly oriented, embryonic/larval trachea that arises from a bifurcation of the cerebropharyngeal branch and targets (tracheates) the brain.[ FlyBase:FBrf0064787 ]
Also Known As "CB" ; "cerebropharyngeal (posterior) branch" ; "dorsal cervical posterior branch"
Comment To note that the dorsal cervical posterior pupal trachea (FBbt:00002968) corresponds to the pupal pharyngeal branch, not the pharyngeal branch, following figure 23 in of Manning and Krasnow (1993) and figure 2 of Whitten (1957) - FBrf0011558.
