STUDIES ON THE ANATOMY AND HISTOLOGY OF THE FOREGUT IN ORCHESTIA PLATENSIS KRYER (CRUSTACEA : AMPHIPODA) | UTTAR PRADESH JOURNAL OF ZOOLOGY
Orchestia platensis' digestive tract is a straight tube with a foregut, midgut, and hindgut. The foregut is divided into three sections: the oesophagus, the cardiac stomach, and the pyloric stomach. The oesophagus and ston have comparable histological features: chitinous intima, columnar epithelium, tunica prop circular muscles, and occasionally longitudinal muscles.
