Neuro-histochemical observations on the pancreas of Francolinus pondicerianus (grey partridge or safed teeter) as revealed by the cholinesterase technique.

The sharpness in the staining of the neural elements with associated structures was maximum under maintained pH of 5.2, incubation period 19 h and temperature 40 degrees C, by cholinesterase technique. Innervation of the pancreas with reference to blood vessels, pancreatic duct, and islets of Langerhans has been studied in Francolinus pondicerianus (grey partridge or safed teeter). The fibres of the periarterial plexus, periductular plexus and the periinsular plexus were closely related to each other and were finally connected to the ganglia. Ganglia were distributed in the lobular cells and connective tissue space. They were large, small and medium and varies in shape, being rounded, oval, and elongated. Distribution of AChE activity was observed in various ganglia, nerve cells, and nerve fibres.
