“…Uma das principais características morfológicas da lín-gua de ruminantes é a presença do toro lingual bem desenvolvido, presente no terço posterior da superϐície dorsal. Essa protuberância é identiϐicada na língua dos herbívo-ros que se alimentam de vegetação ϐibrosa, incluindo os bovinos (Barros et al 2006), rinoceronte negro (Emura et al 2000), búfalo iraniano (Mahabady et al 2010), ovinos (Tadjalli & Pazhoomand 2004), cervídeos (Zheng & Kobayashi 2006) e camelos (Eerdunchaolu et al 2001) e parece possuir importante papel na mastigação, uma vez que auxilia a pressionar o alimento contra o palato. Ao contrário de descrições anteriores que relatam a presença de papilas ϐiliformes, cônicas e lentiformes no toro da língua de caprinos e bovinos (Chamorro et al 1986, Kurtul & Atalgin 2008, o presente estudo não evidenciou a presença de papilas ϐiliformes nas línguas estudadas, somente lentiformes, cônicas e valadas.…”

“…Sua distribuição é aleatória sobre a superϐície dorsolateral do ápice e corpo da língua e exclusivamente na parte lateral do toro lingual. Resultado semelhante foi relatado por Emura et al (2000) e Zheng & Kobayashi (2006) ao estudarem as línguas de rinocerontes negros e cervídeos, respectivamente.…”

“…Um ϐino epitélio corniϐicado recobrindo as papilas fungiformes, com botões gustativos distribuídos aleatoriamente e se abrindo na superϐície dorsal da papila observados no presente estudo são achados semelhantes aos da língua dos cervídeos (Zheng & Kobayashi 2006), cabras (Igbokwe & Okolie 2009), camelos (Eerdunchaolu et al 2001) e bú-falos (Mahabady et al 2010). Em contraste, esses botões gustativos não foram observados na superϐície livre das papilas da língua dos búfalos iranianos.…”

“…Nos mamíferos domésticos, esse sistema é constituído por quatro tipos principais de papilas: ϐiliformes, fungiformes, valadas e foliáceas. Notavelmente, animais herbívoros possuem papilas ϐiliformes, fungiformes e valadas, mas lhes faltam as papilas foliáceas (Zheng & Kobayashi 2006). As papilas ϐiliformes, cônicas e lentiformes possuem funções mecânicas, enquanto que as fungiformes, valadas e foliáceas possuem função gustativa (Konig & Liebich 2004).…”

Pesq. Vet. Bras. 31(Supl. The morphology of the lingual papillae of domestic goat (Capra hircus) was studied by scanning electron microscopy (SEM) and light microscopy (LM). Filiform, conical and lentiform papillae exert mechanical function whereas fungiform and valate papillae have gustative function. Filliform papillae were distributed all over the lateral and dorsal surfaces of the tongue. They present a conical shape with the thin ends pointed caudally; and possess several secondary processes, of different sizes, with the same orientation. Histological examination of these papillae revealed abundant queratinized tissue. Fungiform papillae were observed on the dorsal and lateral surface of the apical region and body of the tongue. Present a fungi-like shape, with a thick corniϐied epithelium and taste buds distributed on the surface. Lentiform papillae were distributed over the median line of the dorsal torus, presenting projections above the surface of the tongue. Some displayed pyramidal shapes; other were more ϐlattened. Valate papillae were observed on the lateral surface of the posterior part of the torus and present a rounding shape delimited by a deep groove. These papillae possess taste buds on their lateral wall that open up on the groove. Conical papillae were observed on the lingual torus and present an extended shape, with a wide base and a blunt tip. Although the main morphological and structural characteristics of the lingual epithelium are species-speciϐic, some features may be inϐluenced by the type of food and alimentary habits. Therefore, the present study provides a histological and ultrastructural description of the tongue of the domestic goat fed with mixed food (grass and concentrate).INDEX TERMS: Tongue, lingual papillae, scanning electron microscopy.

“…The lenticular papillae were restricted to the lingual prominence, similar to other ruminants, roan antelope, and sitatunga (Emura et al, 2011a,b). There are no lenticular papillae in the lingual prominence of reeves filiform papillae, barking deer, or mazama species (Zheng and Kobayashi, 2006;Adnyane et al, 2011;Kokubun et al, 2012). The conical and lenticular papillae aid mastication and the movement of food inside the buccal cavity and may be related to the need for physical mastication of plant material.…”

Summary:The mammalian tongue has different functions for feeding. We investigated the morphological characteristics of the surface of the tongue of Egyptian buffalo (Bubalus bubalis) using scanning electron microscopy. The lingual surface exhibited different degrees of specialization. The tongue can be divided into the apex, body, and root. The lingual prominence was observed on the posterior area of the lingual body. The lenticular, conical, and vallate papillae were observed on the caudal part of the tongue. The filiform papillae were lingual papillae covering the entire dorsal and ventral surface of the tongue at the lingual apex; they consisted of a main process that functions to transport food materials towards the pharynx. The fungiform papillae were dispersed between the filiform papillae. Large lenticular papillae were found at the lingual prominence. The highly keratinized lenticular papillae aid the physical mastication of plant materials. Twelve vallate papillae were arranged in V shape on the lingual root. These anatomical characteristics of the lingual surface of Egyptian buffalo may enhance understanding of its feeding behavior adaptations.

We observed the three-dimensional structures of the external surface and connective tissue cores CTCs, after exfoliation of the epithelium of the lingual papillae (filiform, fungiform, and foliate papillae) of the common hippopotamus (Hippopotamus amphibius amphibius) using scanning electron microscopy and conventional light microscopy. Following unique features were found; typical vallate papillae with a circumferential furrow were not observable. Instead, numerous large fungiform papillae were rather densely distributed on the posterior of the lingual prominence. Taste buds were observable only on the dorsal epithelium. Serous lingual gland was not seen in the lamina propria; however, mucous-rich mixed lingual glands were found and in a few of orifices were seen on the large fungiform tops. Lingual prominence was diminished their width. Rather long and slender conical papillae were distributed on the lingual prominence and were similar to nonruminant herbivore, that is donkey. Beside this narrow lingual prominence, lateral slopes were situated with numerous short spine-like protrusions. After removal of the epithelium, CTCs of lateral slopes exhibited attenuated flower bud structures. Large-conical papillae were situated on the root of the tongue. These large conical papillae were not seen among ruminants and seen on the lingual root of omnivores and carnivores. It implies that lingual structure of common hippopotamus possessed mixed characteristics between Perissodactyls, Ruminantia, and nonherbivores such as Suiformes because of their unique evolutionally taxonomic position. Moreover, adaptation for soft grass diet and associating easier mastication may be also affecting these mixed morphological features of the tongue. Anat Rec, 292:921-934, 2009.
