In two dogs the larynx was videotaped simultaneously via a telescope. Increased CT activity was induced by airway occlusion or hypercapnia. Observations were carried out before and during cold blockade of the recurrent laryngeal nerve (RLN) or the nerve to the CT (external branch of the superior laryngeal nerve [Ext SLN]). Paralysis of the CT had no effect on laryngeal resistance or glottic area, even at very high levels of CT activity. Blockade of the RLN increased inspiratory resistance, but did not have a significant effect on expiratory resistance. Electrical stimulation of the Ext SLN produced tetanic CT contraction, which increased laryngeal resistance in both inspiration and expiration. This was true even at very high levels of PCA activity. These results indicate that although artificially induced CT contraction markedly affects laryngeal resistance, physiologic levels of respiratory activity do not have a significant effect.<\/jats:p>","DOI":"10.1177\/000348948909800207","type":"journal-article","created":{"date-parts":[[2014,10,3]],"date-time":"2014-10-03T14:35:41Z","timestamp":1412346941000},"page":"119-124","source":"Crossref","is-referenced-by-count":23,"title":["Effects of Cricothyroid Muscle Contraction on Laryngeal Resistance and Glottic Area"],"prefix":"10.1177","volume":"98","author":[{"given":"Gayle E.","family":"Woodson","sequence":"first","affiliation":[{"name":"San Diego, California"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oommen","family":"Mathew","sequence":"additional","affiliation":[{"name":"Galveston, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Franca","family":"Sant'Ambrogio","sequence":"additional","affiliation":[{"name":"Galveston, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Sant'Ambrogio","sequence":"additional","affiliation":[{"name":"Galveston, Texas"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[1989,2,1]]},"reference":[{"key":"bibr1-000348948909800207","first-page":"135","volume":"74","author":"Rudomin P","year":"1966","journal-title":"Arch Int Physiol Biochim"},{"key":"bibr2-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-196107000-00002"},{"key":"bibr3-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1177\/000348947007900517"},{"key":"bibr4-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(77)90129-8"},{"key":"bibr5-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1177\/000348947808700318"},{"key":"bibr6-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1016\/0034-5687(86)90084-8"},{"key":"bibr7-000348948909800207","first-page":"93","volume-title":"Laryngeal function in phonation and respiration","author":"Woodson GE","year":"1987"},{"key":"bibr8-000348948909800207","author":"Mathew OP","journal-title":"Ann Otol Rhinol Laryngol"},{"key":"bibr9-000348948909800207","author":"Woodson GE","journal-title":"Ann Otol Rhinol Laryngol"},{"key":"bibr10-000348948909800207","first-page":"335","volume":"39","author":"Sherry JH","year":"1980","journal-title":"Respir Physiol"},{"key":"bibr11-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1152\/jappl.1984.56.2.500"},{"key":"bibr12-000348948909800207","first-page":"80","volume-title":"Laryngeal function in phonation and respiration","author":"Sherry JH","year":"1987"},{"key":"bibr13-000348948909800207","doi-asserted-by":"publisher","DOI":"10.3109\/00016486909125491"},{"key":"bibr14-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-197010000-00001"},{"key":"bibr15-000348948909800207","volume":"41","author":"Faaborg-Andersen KL","year":"1957","journal-title":"Acta Physiol Scand"},{"issue":"1","key":"bibr16-000348948909800207","first-page":"1","volume-title":"Techniques in respiratory physiology","author":"Sant'Ambrogio G","year":"1984"},{"key":"bibr17-000348948909800207","first-page":"120","volume-title":"Neurolaryngology","author":"Sato F","year":"1987"},{"key":"bibr18-000348948909800207","first-page":"463","volume":"18","author":"Grossman M","year":"1906","journal-title":"Arch Laryngol Rhinol"},{"key":"bibr19-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1177\/000348944805700401"},{"key":"bibr20-000348948909800207","first-page":"444","volume-title":"Diseases of the nose, throat and ear","author":"Ballenger JJ","year":"1977"},{"key":"bibr21-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1957.03830200029004"},{"key":"bibr22-000348948909800207","doi-asserted-by":"publisher","DOI":"10.1177\/000348948709600512"}],"container-title":["Annals of Otology, Rhinology &amp;
