The movies show the reconstructed larynx of four rodent species in 3-D. Initially, all cartilages and the airway are shown. Then, the main cartilages disappear and only the airway and the alar cartilage remain. In all four species, the cartilaginous framework of the larynx consists of thyroid cartilage, epiglottis, a pair of arytenoid cartilages, and cricoid cartilage. The three muroid species also possess an alar cartilage that was not present in Dipodomys.
