“…The rounded shape presented in the papillae of this study was different from those found in other hebivores such as the Pantanal deer, having a flattened shape and mouse deers, which had flat and elongated papillae (AGUNGPRIYONO et al, 1995;MACHADO, 2016).…”

ABSTRACT:The present study aimed to describe the disposition and amount of circumvallate lingual papillae in Saanen goats using 26 goat tongues from the Laboratory of Animal Anatomy and Morphology of the Federal Rural University of Rio de Janeiro, which were previously fixed in 10% formaldehyde solution for later dissection of tongues that were removed from the oral cavity for the necessary studies. After identification, morphometric data were tabulated and submitted to statistical analysis for further description. In descriptive statistics, the mean of 17.85 was close to the median of 17.5 and the overall dispersion (standard deviation) was relatively low (2.24), which represents a coefficient of variation (CV) of 12.8 %. Confidence interval for mean with 95 % with 99 % confidence was also performed. Regarding the distribution of papillae, 21 tongues (80.7 %) of the total samples were located on the side of the tongue root, 3 tongues (11.5%) were distributed on the side of the tongue root, migrating toward the tongue median sagittal plane, 1 tongue (3.8 %) was located in the concave position on the side of the tongue root and 1 tongue (3.8 %) was disposed on the sides of the tongue, with some papillae arranged close to the region of the tongue median sagittal plane.

The tayra (Eira barbara) is a mammal belonging to the Mustelidae family that occurs in all Brazilian biomes. The present work aimed to describe the morphology of the tongue of these specimens highlighting their structures and particularities that will serve as a subsidy to elucidate the anatomy of the same and for comparative studies among other species of domestic and wild animals. Five adult male specimens of E. barbara were studied, which were fixed using 10% aqueous formaldehyde solution. The tongue was removed by opening the oral cavity and separating the maxillary/mandible bone complex. Being in possession of the material, photodocumentations and collection of the fragments were made for the proper preparation of histological slides and Scanning Electron Microscopy (SEM). The lingual papillae found in tayra were mechanical: filiform and conical; and gustative: fungiform and circumvallated. Histologically, the papillae are constituted by keratinized stratified epithelium and in the innermost region, it was composed of tissue connective dense unshaped followed by a layer of muscle bundles of skeletal striated. In the region of the root of the tongue of E. barbara, there were a set of small mixed salivary glands (serous and mucous) and the punctual presence of gustatory corpuscles at the level of epithelium. The morphological description of the E. barbara tongue revealed similarity to that described in literature for other domestic and wild mammals. However, the particularity of the absence of foliate papilla and the quantitative of four papillae circumvallate in the region of the root of the tongue of this species.
