Vagal mucosal arbors are afferents that arborize deep in the mucosal layer and send a subset of their branches paralleling the gastric glands and reaching the basal side of the epithelial wall in direct contact with the contents of the stomach. Panel A illustrates a dextranbiotin filled mucosal arbor (brown branches) in the mucosal layer. Panel B illustrates how the mucosal fibers branch and ramify in the deeper mucosal layers in the zone heavily populated with EEC (in the specimen in panel B, the brown dextran-biotin labeled afferent articulates with EEC immunohistochemically stained for gastrin (steel gray secondary)). Scale bars = 100 μm.
