Study on the formation of neural network in the tongue of Gallus domesticus (White Leghorn) as revealed by cholinesterase technique.

The neural network in the tongue of Gallus domesticus was visualized using a cholinesterase technique. The network of acetylcholinesterase positive nerve fibres was formed by the tortuous myelinated as well as non-myelinated, preganglionic and postganglionic nerve fibres. The network was closely associated with a chain of acetylcholinesterase positive ganglia, the nerve fibres of the fungiform, filiform, circumvallate and foliate papillae and with the fibres of the neural terminal network.
