General Information
Term embryonic/larval middle midgut ID (Ontology) FBbt:00001884 (Fly Anatomy)
Definition Central part of the embryonic/larval midgut. This region is acidic (Filshie et al., 1971; Shanbhag and Tripathi, 2009). The epithelium of the anterior part consists of alternating copper cells and interstitial cells (Poulson and Bowen, 1952; Filshie et al., 1971; Shanbhag and Tripathi, 2009). Immediately posterior to this is a region of large flat cells (Poulson and Waterhouse, 1960). Posterior to this, the most posterior part of the middle midgut consists of iron accumulating cells (Poulson and Bowen, 1952).[ FlyBase:FBrf0008422 FlyBase:FBrf0013091 FlyBase:FBrf0023227 FlyBase:FBrf0064792 FlyBase:FBrf0208023 ]
