Term pharyngeal tracheal branch ID (Ontology) FBbt:00000394 (Fly Anatomy)
Definition Embryonic/larval trachea that arises from a bifurcation of the cerebropharyngeal branch and targets (tracheates) the pharynx.[ FlyBase:FBrf0064787 ]
Also Known As "cerebropharyngeal (anterior) branch" ; "dorsal cervical anterior branch" ; "PB"
Comment To note that the dorsal cervical anterior pupal trachea (FBbt:00002966) corresponds to the pupal cerebral branch, not the pharyngeal branch, following figure 23 in of Manning and Krasnow (1993) and figure 2 of Whitten (1957) - FBrf0011558.
