General Information
Term middle midgut ID (Ontology) FBbt:00047108 (Fly Anatomy)
Definition Central part of the midgut. This region is acidic. The epithelium of the anterior part consists of alternating copper cells and interstitial cells. Posterior to this is a region containing large flat cells.[ FlyBase:FBrf0008422 FlyBase:FBrf0013091 FlyBase:FBrf0023227 FlyBase:FBrf0064792 FlyBase:FBrf0208023 FlyBase:FBrf0216495 FlyBase:FBrf0221749 ]
