Using histochemical NADPH-diaphorase reaction NO-ergic neurons distribution in human tracheobronchial tree was studied in man and mammals. Psedounipolar sensory neurons forming microganglia mark in adventitia of the trachea posterior surface from superior border up to trachea bifurcation. It was suggested that protoneurons are the constant structural formations of respirator organs. Their capacity to exert effector influence on the tissue through axon-reflex mechanism, apart from their sensory function is under discussion.
