Observations on the intrinsic innervation of the islet of Langerhans of Rattus rattus rufescens (Indian black rat).
The innervation of Langerhans' islets appeared rather profuse. Generally the nerve fibres of the peri-insular plexus formed a basket enveloping the islet of Langerhans. The peri-insular ganglia were occasionally seen. No autonomic interstitial cells of Cajal nor nerve endings were observed in the islet of Langerhans, due to the thickness of the sections. The 'complexes sympathico-neuro-insulaires' were occasionally seen. The plexuses and neural terminal network were seen connected to each other; thus they are not separate entities.
