RESUMO

A method for injecting a small quantity of tritiated leucine directly into the nodose ganglion of the adult hen is described. The presence of an inner and an outer nerve plexus in the trachea and extrapulmonary primary bronchus is confirmed. Structures in the luminal epithelium of the trachea, syrinx and extrapulmonary primary bronchus having an afferent innervation are described and their possible function is discussed. The question of positive chemography in autoradiographic studies is discussed.
