The soft palate and larynx play an important role in respiration and phonation, regulating the airflow in the upper airway. The levator veli palatini muscle (LVP) is the principal muscle responsible for generating palatal movements. The lateral cricoarytenoid muscle (LCA) is a laryngeal adductor muscle, and the posterior cricoarytenoid muscle (PCA) is a laryngeal abductor muscle. This study was designed to define, by electromyographic techniques, the coordination between palatal and laryngeal muscle activities in response to rebreathing and lung inflation. We performed tracheotomies on 12 mongrel dogs anesthetized with sodium pentobarbital and compared the effects of rebreathing and lung inflation on LVP activities with those on LCA and PCA activities. During rebreathing, expiratory LVP and inspiratory PCA activities were progressively augmented, but expiratory LCA activity was inhibited. On the other hand, lung inflation caused augmentation of LVP and LCA activities. In contrast, lung inflation inhibited PCA activity. We thus concluded that LVP activity coordinates with PCA activity in response to alternation of Paco2 and Pao2 levels, while it coordinates with LCA activity in response to lung inflation.
