Comparative neurohistological observations on the pancreatic duct in certain birds and mammals as revealed by cholinesterase technique.

A comparative study of pancreatic duct innervation of Francolinus pondicerianus (grey partridge or safed teeter) and Suncus murinus (Indian musk shrew) as revealed by cholinesterase technique has been done for investigation. In Suncus pancreas, the AChE-positive ganglia, elongated and irregularly shaped, medium and large-sized, were recorded either on the periphery of the excretory duct or on the wall of the duct. No ganglia were recorded on the periphery, although the fibres of the ganglia were in close association with the periductular plexus and the fibres of the peri-insular plexus in Francolinus. In Suncus, multipolar and AChE-positive ganglia of various shapes, arranged in chain-like fashion on the duct, were recorded, whereas in Francolinus the multipolar ganglia of AChE-positive nature and of various shapes, arranged in chain-like fashion, were observed in the duct region.
