“…The simple structure of these filiform papillae on the anterior dorsal area is very similar to those found rodents such as; rats (Iino et al, 1988), mice (Kobayashi et al, 1989c), hamsters (Kitajima et al, 1992) and bank vole (Jackowiack and Godynicki, 2005) as well as insectivores such as moles (Miyata et al, 1990), and the suncus murinus (Kobayashi et al, 1989b). In contrast, the filiform papillae of artiodactyla, carnivores and primates vary in shape and consist of a main process and on average have between 10 to 20 accessory processes (Asami et Kobayashi et al, 1989aKobayashi et al, , 1994Kobayashi et al, , 1995Kobayashi et al, , 1997.…”

“…The number of taste buds on the upper part of the fungiform papillae varies between animal species. Animals which have one taste bud on each fungiform papilla include rodentia (rats (Iino et al, 1988), mice (Kobayashi et al, 1989c), hamsters (Kitajima and Kobayashi, 1992)) and the suncus murinus (Kobayashi et al, 1989b) (insectivora). Moles (Miyata et al, 1990) (insectivora) have one to three taste buds on each fungiform papilla.…”

“…It is also accepted that not only the external form of lingual papillae but also the stereo structure of their CTCs retain a structure that is characteristic of each animal species (Kobayashi and Iwasaki, 1989). The morphological characteristics of lingual papillae have been studied in some animals such as rodents (rats, mice, hamster, bank vole, beaver) (Kutuzov and Sicher, 1951;Iino and Kobayashi, 1988; Kobayashi et al, 1989c;Kitajima et al, 1992; Jackowiack and Godynicki, 2005; Shindo et al, 2006), insectivores (moles, suncus) (Kobayashi et al, 1989b;Miyata et al, 1990), carnivores (raccoon dog, fox, silver fox, tiger) (Emura et al, 2004(Emura et al, , 2006; Jackowiack and Godynicki 2004), artiodactyl (Asami et al, 1995;Agungpriyono et al, 1995;Zheng et al, 2006), and primates (Kobayashi et al, 1989a; Kobayashi and Wanichanon, 1992). Rabbit tongues have been useful for morphological studies.…”

Summary:The morphological structure of the lingual papillae and their connective tissue cores (CTC) in a rabbit were studied using LM and SEM and were compared to that of other animal species. Externally, the filiform papillae distributed on the anterior surface of the dorsal tongue were short and conical with a round base and had a flat area on their anterior upper half. The CTC of the conical filiform papillae had a roughly triangular plate-like structure with a round top. Several small round protrusions were found on both inclined planes of the triangle. Spearhead-like filiform papillae were distributed on the anterior edge of the lingual prominence and branched filiform papillae were on the posteriorly wide area of the prominence. These papillae on the prominence had a slightly ramified CTC that differed from that of the CTC of the conical filiform papillae distributed on the anterior tongue. Dome-like fungiform papillae were distributed among the conical filiform papillae of the anterior tongue and had a CTC with a roundish structure that was almost but, not quite spherical in appearance with 1 to 10 small round concave indentations for taste buds on their upper surface. The foliate papillae had approximately 15 parallel ridges separated by grooves. These ridges contained a parallel thin plate-like CTC exhibited after removal of the epithelium. The vallate papilla was comprised of a spherical central papilla and had a circular wall with a flower-like CTC almost resembling a carnation.The stereostructure of the rabbit's filiform CTC are comparatively described as being morphologically in between those of rodents and those of the guinea pig and Japanese serow. Such evolution has probably occurred due to the species unique masticatory and gustatory needs and functions.

“…The CTCs of FiP of hamsters [a insectivore mole] and the Cape hyrax are conical-shaped with a semicircular concavity on the anterior surface [27,39,40]. Though the descriptions are slightly different from each other, their shapes are similar to the CTC shape of the round tip FiP observed in the present study.…”

Objectives:To clarify the morphology of the tongue papillae formation and the metabolic characteristics along the papillae distribution in rats. Methods: The experiment was designed as a cross-sectional study and included; a scanning electron and light microscopic examination, connective tissue core analysis, and an enzyme activity test on rat tongue samples of the embryonic (n = 60) and postnatal (n = 12) periods. Results: The primordium of fungiform papillae (FuP) was already formed on embryonic day 15 (E15), and filiform papillae (FiP) was formed on E17. In the postnatal period, the middle and posterior parts of the tongue quickly developed toward the anterior part of the oral cavity. Three types of FiP were found: round, conical and branched. According to the enzyme activity test, all energy, lipid, protein and sugar metabolic enzymes showed significant differences along the tongue parts. Conclusion: No positional difference was found in the morphology of rat tongue papillae during the embryonic period. During the postnatal period, the morphology and enzyme activities of the tongue mucosa displayed differences expressing tongue development and its functional characteristics among the described tongue parts-listed above.

“…No entanto, não possuem a eminência intermolar, bem delimitada como na espécie em questão. Esta estrutura é uma característica da língua dos ornitorrincos (SONNTAG, 1920), dos coelhos (KULAWIK; GODYNICKI, 2007a;2007b), roedores (IINO; KOBAYASHI, 1988;KITAJIMA;KOBAYASHI, 1992) e ungulados (ASAMI et al, 1995;ABD-ELNAEIN et al, 2002). Ainda quanto ao sulco terminal observado na paca e em outros roedores, este também está presente em cães, porém, é referido como sulco mediano e está relacionado à inserção de alguns músculos extrínsecos da língua, os quais, juntamente com os músculos intrínsecos, são responsáveis pelos movimentos de protrusão e retração desse órgão (SCHWARZE; SCHRÖDER, 1970;FRANDSON, 1979;NICKEL et al, 1979;SISSON, 1986;DYCE et al, 1997;KONIG;LIEBICH, 2004); acredita-se que na paca, este sulco executa a mesma função.…”

ResumoEste artigo descreve a morfologia da língua, seus músculos extrínsecos e as características das papilas linguais de Cuniculus paca. Foram utilizados quinze espécimes provenientes do Setor de Animais Silvestres da Universidade Estadual Paulista (UNESP). Nessa espécie, a língua se divide em três regiões: raiz, corpo e ápice. Este último é delimitado pelo frênulo lingual, que possui aspecto de membrana fibrosa. Identificou-se também um sulco mediano e uma proeminência em sua superfície dorsal. Os músculos extrínsecos da língua são o estiloglosso, hioglosso, genioglosso, gêniohioide e milohioide, estes dois últimos inseridos no aparelho hioide. Quanto à presença de papilas linguais, em todos os espécimes se observou cinco tipos de papilas: filiforme, fungiforme, valada, folheada e cônica. As papilas filiformes distribuem-se por toda a superfície do ápice e corpo da língua. São inclinadas caudalmente por todo o corpo, até que se modificam na região da raiz e formam as papilas cônicas. As papilas fungiformes distribuem-se em grande quantidade no ápice lingual, entre as papilas filiformes. Esse tipo de papila possui formato semelhante a cogumelos. Apenas duas papilas valadas estão localizadas na porção caudal da raiz lingual, possuem formato ovalado e estão envolvidas por um sulco profundo. As papilas folheadas apresentam-se em sulcos ou ranhuras paralelas localizadas na porção lateral da língua, entre as papilas valadas e a metade da proeminência intermolar. Na raiz, corpo e ápice da língua foi observado epitélio do tipo estratificado pavimentoso queratinizado, que reveste tanto as papilas linguais como a superfície entre elas. Palavras
