“…Observing the fungiform papillae regarding the location, Benetti et al (2009) in Bradypus toquartu demonstrated that these are situated at the lateral margin of the tongue apex, similar to the species of our study, but on Bradypus variegatus, the fungiform papillae, besides being agglomerated on the tongue apex, are also located distributed in the dorsal surface of the tongue, as is reported in C. vellerosus armadillos (Estecondo et al, 2001), C. villosus and Zaedyus pichiy (Ciuccio et al, 2008), besides other mammals, such as rodents, omnivorous and carnivorous (Jackowiak and Godynicki, 2004). In Saimiri sciureus (Branco et al, 2011) these papillae are distributed all over the tongue and there are no specific concentration points.…”

“…Our results on the scanning electron microscope showed that filiform papillae were distributed all over the dorsal region of the tongue, but in a most dense way in the apex and body, being disposed around the fungiform papillae, as it was already reported by several authors (Morais et al, 1994;Watanabe et al, 1992;Jackowiak and Godynicki, 2004).…”

“…According to findings by Jackowiak and Godynicki (2004), the presence, distribution and structure of the taste buds are correlated to the feeding habits of the animal, and it can vary and suffer adaptations (Pastor et al, 2008). Doran and Baggett (1971) concluded that the tongue of mammals can be divided in two functional categories, each one with a clear morphological correlation.…”

“…The tip of the tongue can be considered a sensorial organ (Agungpriyono et al, 1995) and the probable cause for such fact is due to the big number of gustatory pores present in this region. In studies with other mammals, Jackowiak and Godynicki (2004) related the tip of the tongue with the preliminary analysis of the food tasting.…”

The Bradypus variegatus inhabits the forests of South America and feeds from leaves, branches and sprouts from different plants. Due to its diet and the lack of literature on the morphological aspect of Xenarthras, five Bradypus variegatus tongues from animals which died from natural causes were evaluated, and they came from Pará State Museum Emílio Goeldi and were donated to the Laboratory of Animal Morphological Research (LaPMA) from UFRA, for revealing the different types of papillae and epithelial-connective tissue. Macroscopically, the tongues presented elongated shape, rounded apex, body, root, median sulcus in the root's apex, and two vallate papillae. The mucous membrane of the tongue revealed a keratinized stratified pavement epithelium, while the ventral surface of the tongue was thin and smooth, not provided with any type of papillae. However, the dorsal surface of the tongue was irregular with the presence of three types of papillae: filiform, fungiform and vallate papillae. The filiform papillae found were of a simple type, presenting a rounded base, irregularly distributed with a larger concentration and development on the tongue's apex and body. The fungiform papilla showed a practically smooth surface with irregular format, with the presence of gustatory pores; these were found all over the dorsal surface, with larger concentration at the rostral part of the apex. Only two vallate papillae were observed disposed in the root of the tongue, surrounded by a deep groove, and revealing several taste buds. The tongues from Bradypus variegatus presented gustatory papillae similar to the ones described for other Xenarthras species and wild mammals. Keywords: morphology, lingual papillae, Bradypus variegatus RESUMO A Bradypus variegatus habita florestas da América do Sul e alimenta-se de folhas, ramos e brotos de várias plantas. Em decorrência de sua dieta, bem como da escassez de literatura sobre aspectos morfológicos dos Xenarthras, avaliaram-se cinco línguas de Bradypus variegatus, que foram a óbito por causas naturais, provenientes do Museu Paraense Emílio Goeldi e doados ao Laboratório de Pesquisa

“…Jackowiak and Godynicki (2005) reported that the orifices of the anterior glands were situated on the lateral surfaces of the posterior part of the lingual body, whereas the posterior lingual glands open on the entire surface of the lingual root. In the mammals, some openings of the glandular ducts at the dorsal surfaces of the conical papillae of the lingual radix were observed in the tiger (Emura et al, 2004), fox (Jackowiak and Godynicki, 2004) and mole (Jackowiak, 2006). In the tongues of the peregrine falcon and common kestrel, the many openings of the lingual glands existed in the entire surfaces of the lingual body and lingual root.…”

The studies on the structure of the tongue in birds have been conducted on a small number of species, i.e. chickens, parrot, geese, eagle and cormorant (Iwasaki and Kobayashi, 1986;Homberger and Brush, 1986;Iwasaki et al., 1997;Jackowiak and Godynicki, 2005;Jackowiak et al., 2006). The results of morphological studies conducted so far indicate a close correlation of the shape of the tongue with the method of food intake and the type of food, and habitat.However, no scanning electron microscopic (SEM) study of the tongue of the owl has been carried out. The purpose of this study is, therefore, to examine threedimensionally the dorsal lingual surface of the owl, in order to compare the results with those previous reports in other birds. Materials and MethodsThe tongues of an adult peregrine falcon (Falco peregrinus) and common kestrel (Falco tinnunculus) of the family Falconidae were used in this study. The tongues were fixed in 10% formalin. Small blocks containing papillae were cut with a razor blade, post-fixed with 1% osmium tetroxide for 1 h. Thereafter, the specimens were dehydrated through graded series of acetone and criticalpoint-dried. To show the three-dimensional connective tissue structure of the lamina propria of the mucosa, some of the samples were washed in distilled water after fixation and macerated in 3.5N HCl at room temperature for 6 days. After maceration tissues were washed in the distilled water and post-fixed in 1% osmium tetroxide for 1 h, and dehydrated in a series of acetone and criticalpoint-dried. All specimens were sputtered with Pt-Pd before being examined under SEM (Hitachi S-3500N, Tokyo, Japan) at an accelerating voltage of 15 kV. ResultsThe tongue of the adult peregrine falcon is about 2.5 cm long. The tongue of the adult common kestrel is about 1.5 cm long. The tips of the tongues of the peregrine falcon and common kestrel were bifid ( Fig. 1 and 3). Three parts are distinguished in the dorsal surface of the tongue: the apex, the body and the root of the tongue in each bird ( Fig. 1 and 3). The region of the openings of the lingual glands between the lingual apex and lingual root are very wide area (Fig. 1, 2c, 2d, 3, 4c and 4d). Many conical papillae of the lingual body are inclined toward the posterior of the tongue on the posterior end (Figs. 1, 2e, 2f, 3, 4e and 4f). At low magnification of scanning electron microscopy, many processes are observed densely distributed over the entire lingual apex of the dorsal surface ( 11

The structure of the tongue of the marsupial feathertail glider (Acrobates pygmeus) was observed under a light and scanning electron microscope. The elongated tongue with a sharpened apex is ca. 10 mm in length. Only the posterior half of the tongue is attached to the bottom of the oral cavity by the frenulum, which facilitates considerable mobility of the anterior free part of the tongue. On the dorsal surface of the tongue, three types of lingual papillae were distinguished, that is, mechanical filiform papillae and gustatory fungiform and vallate papillae. The arrangement, shape, and size of filiform papillae and the direction of their keratinized processes change depending on the part of the tongue, so that the surface of the apex and the body of the tongue resembles a brush adapted to effective holding of semiliquid food and collection of pollen. The fungiform papillae have a single taste bud and are uniformly scattered between filiform papillae only on the anterior half of the tongue. On the smooth root of the tongue, three oval vallate papillae are arranged in the form of a triangle, similarly as it is the case in other marsupials. The posterior biggest vallate papilla is oriented perpendicularly to the smaller anterior papillae. The results of the study on the feathertail glider show that the special arrangement of lingual papillae is strongly adapted to feeding behavior of this nectar-eating and frugivorous animal.
