General Information
Term embryonic/larval midgut ID (Ontology) FBbt:00001882 (Fly Anatomy)
Definition Middle part of the embryonic/larval alimentary canal. The midgut runs from the proventriculus to its posterior end, where it meets the hindgut, immediately anterior to the insertion of the Malpighian tubules. In the larva, there are the 4 gastric caeca at the anterior end.[ FlyBase:FBrf0064792 ]
Also Known As "larval midgut" ; "midintestine"
