Abstract

Introduction: The Six-banded armadillo (Euphractus sexcintus) belongs to Cigunlata order, has diverse feeding habits and masticatory apparatus developed. The tongue, one of the major components of this equipment, has the mucosa papillae, taste buds and tongue glands. Materials and Methods: Six-banded armadillo were submitted to an anesthetic protocol with Tiletamine and zolazepan (Telazol ? , Fortdotge, Brazil) and Sodium Thiopental (Thiopentax ? , Cristália, Brazil), we proceeded to euthanasia using Potassium Chloride 19.1%, to then fix them in a 10% formaldehyde solution. The tongues were dissected and identified structures. For microscopic processing, segments from different parts of the tongue were subjected to histological routine and stained with hematoxylin-eosin and Masson. Results: The tongue of the six-banded armadillo presents three types of papillae: filiform, fungiform and vallate, with no conical buds and foliate. Still in the tongue mucosa, was observed mucous glands and various taste corpuscles. Some data differ from those same found in other wild animals that have been studied, but are similar to those of the same phylogenetic. Conclusion: The morphological characteristics of the six-banded armadillo’s tongue are adapted to the difficulties faced by him during chewing, requiring the tongue, structures that provide you mobility, strength and sensitivity.
