Physiology of the lateral cricoarytenoid muscle.

Abstract

A study was made of the mechanical properties of the lateral cricoarytenoid muscle in the dog. This laryngeal muscle was found to have a fast contraction time of 19 msec, which is second only to the very fast thry oarytenoid muscle. An average maximum force of 63 g also would rank this muscle as one of the ‘weaker’muscles of the larynx.
