ABSTRACT:
Detailed muscle information has become increasingly valuable as biomechanical models of the larynx have grown in complexity. For example, it has become progressively important to have more details of laryngeal muscle size, direction, muscle structure, and muscle shape (e.g., shape of muscle at origin and insertion), as well as inter-muscle spatial relations. Presented in this report are data of four male and four female canine larynges. Specifically described are details of the intrinsic abductor and adductor musculature of the canine larynx: the posterior cricoarytenoid, the lateral cricoarytenoid and the interarytenoid muscles. Also presented are the three-dimensional representations of four to five muscle bundles of each muscle. Through the use of this resource, it is expected that biomechanical models of laryngeal mechanisms can take a needed step into realism in order to support and explore clinical phonosurgical therapies. Quantification of vocal fold geometry is necessary for the development of anatomically realistic and consistently defined experimental/computational models of the glottic and subglottic regions. Such models will facilitate the study of the influence of the subglottis in voice production.
