Combined left and right TCDs were measured with linear transducers attached by a thread to the thyroid alae. During tidal breathing via a tracheostomy, phasic inspiratory TCD occurred in all dogs [0.66 +\/- 0.2 mm (mean +\/- SE)] together with phasic inspiratory electromyographic activity in the cricothyroid (CT) and posterior cricoarytenoid (PCA) muscles. During brief tracheal occlusions, TCD increased significantly to 1.27 +\/- 0.2 mm (P = 0.001), accompanied by an increase of 95\u2013115% in the peak CT and PCA electromyograms. Bilateral supramaximal electrical stimulation of the external branches of the superior laryngeal nerve (ExSLN) produced a TCD of 9.9 +\/- 0.8 mm; however, similar stimulation of the recurrent laryngeal nerve (RLN) produced a TCD of only 1.33 +\/- 0.1 mm (P = 0.0001). Furthermore, bilateral section of the ExSLN in five dogs significantly reduced tidal TCD by 48.7 +\/- 24.4% (P &lt; 0.05), and bilateral section of both the ExSLN and RLN resulted in slight phasic inward TCD (-0.06 +\/- 0.05 mm). Thus, it appears that the activities of both the CT and RLN-innervated muscles (probably the PCA muscle) contribute to tidal breathing TCD. These findings suggest that inspiratory dilation of the hypopharynx is mediated by contractions of CT and PCA muscles. <\/jats:p>","DOI":"10.1152\/jappl.1995.78.2.441","type":"journal-article","created":{"date-parts":[[2017,12,22]],"date-time":"2017-12-22T11:19:47Z","timestamp":1513941587000},"page":"441-448","source":"Crossref","is-referenced-by-count":6,"title":["Thyroid cartilage movements during breathing"],"prefix":"10.1152","volume":"78","author":[{"given":"T.
