1 Introduction The ganglionated myenteric and submucous plexuses contain millions of enteric neurons and extend along the length of the GI tract, forming circuits that coordinate gut functions. Different parts of the GI tract perform distinct roles; it may be expected that the circuitry of the enteric nervous system differs between regions. The stomach is a low-pressure reservoir which mixes food with gastric juices and provides controlled release into the duodenum.
