embryonic proventriculus [FBbt_00005607]
Proventriculus of the embryo. It contains three distinct cell layers: inner, intermediate and outer. At the anterior end, corresponding to the most anterior region of the midgut, imaginal cells are found at the level of the intermediate layer.

Anatomy Larva
Proventriculus of the embryo. It contains three distinct cell layers: inner, intermediate and outer. At the anterior end, corresponding to the most anterior region of the midgut, imaginal cells are found at the level of the intermediate layer.
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.
