General Information
Term adult hindgut ID (Ontology) FBbt:00003143 (Fly Anatomy)
Definition Posterior part of the of the adult alimentary canal, extending from the posterior end of the midgut, where the Malpighian tubules meet, to the rectum, including the rectal pouch and rectal papillae (Miller, 1950; Skaer, 1993; Demerec, 1994). It has a characteristic loop morphology that forms independently of the rotation of the genitalia (Gonzalez-Morales et al., 2015).[ FlyBase:FBrf0007735 FlyBase:FBrf0064792 FlyBase:FBrf0075527 FlyBase:FBrf0228784 ]
