General Information
Term tracheal lateral trunk posterior branch primordium ID (Ontology) FBbt:00000244 (Fly Anatomy)
Definition Posteriorly directed ventral branch of the tracheal primordium that gives rise to the posterior portion of the lateral trunk in each tracheal metamere. It arises as the posterior side of a bifurcation at the ventral end of the tracheal primordium during stage 12. It fuses with posterior branch of the lateral trunk of the next segment to its posterior during stage 14 or 15.[ FlyBase:FBrf0064787 ]
Also Known As "LTp"
