General Information
Term embryonic/larval proventriculus ID (Ontology) FBbt:00001871 (Fly Anatomy)
Definition Proventriculus (cardia) of the embryo or larva.
Also Known As "embryonic/larval cardia" ; "larval proventriculus"
Comment This structure is more correctly referred to as the 'cardia'. Strictly, proventriculus refers to a modification of the foregut, just anterior to the stomodeal valve, found in many insects. Drosophila has no such foregut modification (Miller, 1950). However, the term 'proventriculus' is the one most commonly used for this structure.
