The intermediate epithelium lining the larynx of the Suncus murinus

In the larynx of the Suncus murinus the stratified squamous epithelium lines the tip of the caudal surface of the epiglottis and the region close to the vocal process of the arytenoid cartilage, while the ciliated columnar epithelium is located in the laryngeal sac and the dorsal part of the vocal fold. Further, in the transitional zone between the stratified squamous epithelium and the ciliated columnar one there exists the epithelium which shows gradations ranging from stratified squamous through stratified cuboidal to ciliated stratified low-columnar type. It is suggested that the epithelium lining the transitional zone is identical with the "intermediate epithelium" in the mouse nasopharynx and larynx.
