| Sumario: | SUMMARY: The study was undertaken to collect data on morphological features of the larynx of the chinchilla. This larynx is composed by cartilaginous, membranous and muscular portions and has 9 mm of medium lenght. In the lateral wall there are the vestibular and vocal folds; the laryngeal ventricle are present in the region between the vestibular and vocal folds consisting in a moderate depression. The laryngeal epithelium was studied by light and scanning microscopic methods: the surface of the supraglottic space is covered predominantly by stratified epithelium with cobblestone appearance while it may be seen a typical pseudostratified epithelium composed by ciliated and non-ciliated cells on the subglottis area. However, near to the caudal part of the vocal fold the epithelium gradually changes through the stratified squamous to the intermediated type demonstrating paving-stone appearance.The subepithelial layer was composed by elastic and collagen fibers constituting an intricated meshwork. |
