Neurohistological and histochemical observations on the lung of Francolinus pondicerianus (gray partridge or safed teeter) as revealed by the cholinesterase technique.

An investigation was undertaken to demonstrate the neural elements of the lung of Francolinus pondicerianus, from the point of view of neurohistology and histochemistry. The staining of the neural elements was done by the cholinesterase technique with a maintained pH of 5.2, temperature 40 degrees C and incubation period of 19 h. Distribution of nerves in association with bronchial cartilage, pulmonary vessels and bronchi has been described and discussed. The distribution of the ganglia in association with blood vessels, bronchi, cartilage, various plexuses and the neural terminal terminal network has also been described. The innervation of the bronchi and their branches, and formation of the neural terminal network has been studied, as well as the distribution of cholinesterase in bronchi, blood vessels, muscles, ganglia, and nerve fibres.
