title: [The role of pharyngeal muscles in the regulation of airway resistance during inspiration resistive load in rabbits].
abstract: In anesthetised spontaneously breathing rabbits, an increase in the inspiratoryactivity m.genioglossus was greater than a simultaneous increase in the respiratory activity of the diaphragm cluring loaded breathing. A bypass of the air flow via tracheostoma did not affect the response of the m.genioglossus to a resistive load. The difference seems to be due to different functional inputs from the lung mechanoreceptors to phrenic and hypoglossal neuronal pools.
