[Respiratory movements of the facial musculature and respiration resistance].
Experiments were made on tracheotomized anesthetized rabbits. After trachea occlusion the increase in the nostril discharges becomes more remarkable than that in the diaphragm discharges. In the tracheotomized animals, the air passes into the lungs through the trachea. Nevertheless the respiratory movements of the facial muscles are of importance in the compensation of abnormalities caused by the increased respiratory resistance. Prevention of the respiratory movements of the face muscles results in a drastic increase in the inspiratory discharges of the diaphragm.
