[The mechanisms of the rhythmic movements of the tracheal smooth-muscle wall during breathing].
Change of the lumen of respiratory pathways in breathing was shown to be determined by the electric and mechanical activity of the smooth muscle wall. The rhythmic activity of the smooth muscle is formed by the neuronal apparatus of intramural ganglia. The correlation of this apparatus work with the respiratory centre is performed via the efferents of the n. vagus.
