MORPHOLOGICAL STUDY OF THE LARYNX OF CHINCHILLA (Chinchilla laniger)
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...

Larynx Vocal cord Scanning electron microscopy Chinchilla laniger 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.info:eu-repo/semantics/openAccessSociedad Chilena de AnatomíaRevista chilena de anatomía v.17 n.1 19991999-01-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0716-98681999000100006en10.4067/S0716-98681999000100006 |
