Abstract
The distribution of enteroglial cells and enteric neurons (enkephalin and PHI) in wholemount preparations of the layers of the guineapig jejunum were studied by the peroxidaseantiperoxidase method using antisera to S-100b protein, enkephalin and PHI. The enteric nerve plexuses were composed of enteroglial cells and enteric neurons. There was a delicate network of enteroglial cells extending through the myenteric plexus and submucous plexus. The network formed by these nervous plexuses supported the somata and processes of the enteric neurons. In the myenteric ganglia, many somata of enkephalin-immunopositive neurons were present. PHI-immunopositive neurons were found in the submucous ganglia.
