“…The diet of a widely distributed species may vary between different biomes or habitats (Lessa and Geise, 2010).

2012Macroscopic and microscopic analysis of the tongue of the common opossum (Didelphis marsupialis) MICROSCOPY RESEARCH AND TECHNIQUE, HOBOKEN, v. 75, n. 10, pp. 1329-1333 ABSTRACTWe performed a macroscopic and microscopic study of the tongues of common opossums, Didelphis marsupialis, from South America. We studied two males and two females. We collected morphometric data on the tongue with precision calipers. For the light microscopy and scanning electron microscopy analyses, we fixed tissue fragments in 10% formaldehyde and 2.5% glutaraldehyde, respectively. The opossum tongues averaged 5.87 6 0.20 cm in length, 3.27 6 0.15 cm in width at the lingual body, and 3.82 6 0.15 cm in width at the root. The mean thickness of the lingual body was 1.8 6 0.1 cm, and the thickness of the root was 3.82 6 0.15 cm. Sharp filiform papillae were scattered across the entire tongue; conical filiform papillae occurred on the lingual body and tongue tip; fungiform papillae were scattered among the filiform papillae on the lingual body and tongue tip; and there were three vallate papillae at the root of the tongue. We found two strands of papillary projections in the tongue root. Despite the low variability observed in the lingual papillae, the morphological data obtained in this study may be related to the opossum's diverse food habits and the extensive geographic distribution of the species throughout America.

“…Watanabe et al (1995) reveal that in M. fuscata , the fungiform papillae have a diameter ranging from 250 to 350 μm, whereas in S. sciureus , these papillae have an average diameter of 272 μm (Branco et al,2011), revealing in both cases fungiform papillae than those found in C. penicillata (210 μm). As in S. sciureus (Branco et al,2011) and in the dwarf armadillo ( pichiy ) (Ciuccio et al,2008), in C. penicillata , these papillae are distributed in a diffuse, unlike in the white‐lipped peccary ( Tayassu pecari ), which presents these papillae on the middle third of the tongue (Watanabe et al,2009).…”

“…The number of vallate papillae found in C. penicillata is not common, as usual in most species is the presence of one or two pairs, as in the case of white‐lipped peccaries ( Tayassu peccary ) and domestic carnivores (Noden and De Lahunta,1985; Watanabe et al,2009), However, it has been reported, in some rodents, just a unique papilla in dorsocaudal surface and centrally arranged (Stangl and Pfau,1994). Our observation was remarkably contrasted to the 60 vallate papillae found in the black rhinoceros tongue (Emura et al,2000).…”

Callithrix penicillata belongs to the family Callitrichidae, Callithrix genus. They are basically insectivorous, but they consume fruits. The mucosa of the tongue is composed of some papillary types, revealing different levels of expertise. The present study attempted to describe the morphological and ultrastructural aspects of the dorsal surface of the C. penicillata, describing the characteristics and distribution of papillae found. Five tongues of C. penicillata (two females and three males), obtained from breeding colonies of CENP-Ananindeua-PA, died from natural causes. The material was fixed partly in a buffer solution paraformaldehyde 10% and partly in modified Karnovsky solution, divided into apex, body, and root, and then the fragments were used in light microscopy and scanning electron microscopy. The average length of the tongue of the females was 22 mm and for males 20.5 mm. Three types of papillae were described: filiform (along all tissue extension with 154 μm of diameter), fungiform (along all tissue extension with 275 μm of diameter), and vallate (just three units in caudal (dorsal) portion with 672 μm of diameter). Data analysis indicates that the distribution and ultrastructural morphology of the C. penicillata lingual papillae are some similar to other primates.

“…On the other hand, the bundles of nerve fibers of the circumvallated papilla present variability in their branches, giving rise to a complex mesh of sensorial terminals. The presence of these afferent nerve fibers is responsible for achieving the sensory impulse in the tongue mucosa (WATANABE et al, 2009). Given its importance as production animal of oldest domestication and worldwide distribution (FONSECA et al, 2011), more detailed morphological studies providing data of greater clinical and surgical acuity should be conducted for improving technical practices performed in the goat activity.…”

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.
