The afferent
pathways and upper airway receptor locations involved in negative upper
airway pressure (NUAP) augmentation of soft palate muscle activity have
not been defined. We studied the electromyographic (EMG) response to
NUAP for the palatinus, tensor veli palatini, and levator veli palatini
muscles in 11 adult, supine, tracheostomized, anesthetized dogs. NUAP
was applied to the nasal or laryngeal end of the isolated upper airway
in six dogs and to four to six serial upper airway sites from the nasal
cavity to the subglottis in five dogs. When NUAP was applied at the
larynx, peak inspiratory EMG activity for the palatinus and tensor
increased significantly ( P |

cavity to the subglottis in five dogs. When NUAP was applied at the
larynx, peak inspiratory EMG activity for the palatinus and tensor
increased significantly ( P < 0.05) and plateaued at a NUAP of 10
cmH 2 O. Laryngeal NUAP failed to
increase levator activity consistently. Nasal NUAP did not increase EMG
activity for any muscle. Consistent NUAP reflex recruitment of soft
palate muscle activity only occurred when the larynx was exposed to the stimulus and, furthermore, was abolished by bilateral section of the
internal branches of the superior laryngeal nerves. We conclude that
soft palate muscle activity may be selectively modulated by afferent
activity originating in the laryngeal and hypopharyngeal airway.
