Neuron density and distribution of NADPH-diaphorase positive neurons in the human stomach.
Neuron density and distribution of the NADPH-diaphorase positive neurons were studied in the fundus, corpus and antrum of adult human stomach using cresyl violet staining and NADPH-diaphorase histochemistry. The submucous plexus contained significantly less neurons than the myenteric plexus. Submucous NADPH-d positive neurons were mostly located in ganglia close to the circular muscle layer. Myenteric NADPH-d positive neurons represented 50-60% of the neurons in all the three regions; their density, however, was significantly lower in the fundus. NADPH-d positive fibers formed a rich plexus in the innermost portion of the circular muscle layer of the corpus.
