Innervation of an islet of Langerhans in mouse pancreas drawn by Honjin (1956). From the large nerve trunk at one pole of the islet emerges the peri-insular plexus, the peri-insular ganglia (p.i.g.), and the “neural terminal” net in and around the islet. The neural terminal is said to be composed of nerve fibers and interstitial Cajal's cells (in black). Part of the islet has been excised to show the interior structure of the islet. c = capillary, × 800. (From Honjin, 1956; courtesy of John Wiley & Sons, Inc).
