The key idea is the two main enteric nerve networks and where they sit in the gut wall. Meissner’s plexus, also known as the submucosal plexus, sits in the submucosa, right beneath the mucosa and above the circular muscle layer. This position lets it directly regulate mucosal secretion and local blood flow. In contrast, the myenteric (Auerbach) plexus lies between the circular and longitudinal muscle layers and chiefly coordinates gut motility. So the network located between the circular muscle layer and the mucosa is the Meissner’s (submucosal) plexus.
