General Information
Term adult proventriculus zone 2 epithelial cell ID (Ontology) FBbt:00059332 (Fly Anatomy)
Definition Epithelial cell of the second zone of the adult proventriculus epithelium (King, 1988). This is a columnar cell with irregular cytoplasmic extensions (narrow folds and microvilli) which project into the extracellular material beneath the overlying cuticle. Its basal end is slightly narrower than its apex and inclined posteriorly. There are approximately 600 of these cells in the adult proventriculus (Zhu et al., 2024).[ FlyBase:FBrf0048518 FlyBase:FBrf0258898 ]
