“…Previos studies have reported that conical papillae are located in the middle of the root of the tongue in hazel dormouse (23) and on the intermolar prominence of the root of the tongue in rock cavy (28) and degu (29). The distribution of conical papillae on the tongues of Japanese lesser flying squirrel (17), Jentink's flying squirrel (18) and paca (25) were similar to our study findings. The presence of a thick keratinized layer detected on the epithelial surface of the conical papillae in this study was consistent with the expression of a keratinized layer on the surface of the conical papilla epithelium of tongues in the Jentink's flying squirrel (18) and rock cavy (28).…”

“…In this study, five types of tongue papillae filiform, conical, fungiform, vallate and foliate were detected on the tongue of the squirrel. The shape and distribution of these papillae were similar to the papillae found on the tongue of rats (8), Japanese lesser flying squirrel (17), Jentink's flying squirrel (18), hazel dormouse (23) and paca (25). Filiform papillae were a common and abundant type of papillae on the tongue, extending from the apex to the root.…”

“…Macroscopic and light microscopic properties of both mechanical and gustatory papillae found on tongues of many species belonging to the rodent order were investigated. Accordingly, the macroscopic, light microscopic and scanning electron microscopic structures of the papillae of the mouse (4-7), rat (8)(9)(10)(11), guinea pig (12,13), porcupine (14,15), hamster (16), Japanese lesser flying squirrel (17), Jentink's flying squirrel (18), greater cane rat (19), American beaver (20), capybara (21), agouti (22), hazel dormouse (23), large bamboo rat (24) and paca (25) were examined.…”

This study examined the anatomical and histological features of lingual papillae in squirrels. Two adult male squirrel tongues were used as the material in the study. Three parts were detected in the tongue: apex, corpus, and radix. There was a median sulcus on the apex of the tongue and an intermolar prominence on the body of the tongue. Five types of papillae such as filiform, conical, fungiform, vallate, and foliate were observed on the tongues of the squirrels. Filiform papillae were located from the apex of the tongue to the root as the dominant papilla. Conical papillae were observed on the intermolar prominence, on the sides of the tongue root, and between the vallate papillae. The direction of this papillae was oriented caudomedially. Fungiform papillae were randomly distributed among the filiform papillae. These papillae were mushroom shaped and had slits that separated them from filiform papillae. Three vallata papillae, arranged in a triangle with the apex pointing backward, were found on the root of the tongue. These papillae were surrounded by a trench. Foliate papillae were observed like mucosal folds in the caudolateral part of the tongue. On light microscopic examination, lingual papillae were covered with stratified squamous epithelium and had connective tissues. There were varying degrees of keratinization on the epithelial surfaces of the papillae. Although taste buds were seen in the epithelial layer of the fungiform and vallate papillae, they were not observed in the epithelium of the grooves of the foliate papillae. The findings obtained in the study were compared with those obtained from the lingual papillae of other rodents, and similarities and differences were revealed. Anatomske in histološke značilnosti jezičnih papil na jeziku pri veverici (Sciurus vulgaris) Izvleček: V tej študiji smo preučevali anatomske in histološke značilnosti jezičnih papil pri vevericah. V študiji smo uporabili dva jezika odraslih samcev veveric. Določili smo tri dele jezika: vrh, telo in koren. Na vrhnjem delu jezika je bila sredinska brazda, na telesu jezika pa medmolarna izboklina. Na jezikih veveric smo opazili pet vrst papil: nitaste, konične, gobaste, otočkaste in listaste. Nitaste papile so bile prevladujoče, prisotne od vrha do korena jezika. Konične papile so bile prisotne na intermolarnem izrastku, na straneh korena jezika in med otočkastimi papilami. Usmerjene so bile kavdomedialno. Gobaste papile so bile naključno razporejene med nitastimi papilami. Te papile so bile v obliki gobe z režami, ki so jih ločevale od filiformnih papil. Na korenu jezika so bile tri otočkaste papile razporejene v trikotnik z nazaj obrnjenim vrhom. Obdane so bile z jarkom. Listaste papile so bile v obliki gube sluznice v kavdolateralnem delu jezika. Pod svetlobnim mikroskopom so bile jezične papile pokrite z večskladnim ploščatim epitelijem, imele so vezivno tkivo. Na epitelijskih površinah papil so bile vidne različne stopnje poroženevanja. Čeprav so bile v epitelijski plasti gobastih in otočkastih papil vidne brbončice, jih v epiteliju žlebov listastih papil ni bilo opaziti. Ugotovitve, pridobljene v tej študiji, smo primerjali z ugotovitvami študij jezičnih papil drugih glodavcev ter prikazali podobnosti in razlike med njimi. Ključne besede: svetlobna mikroskopija; jezične papile; glodavec; veverica; brbončica

“…On the other hand, the conical-shaped papillae of the desert hedgehog were distributed on the distal part of the tongue in the small triangular area between the linguae radix in between the three circumvallate papillae, while the distal part was devoid of that type. Similar observations were reported in the lowland paca (Machado et al, 2013), leopard (Sadeghinezhad et al, 2017), and ocelot (Freire et al, 2019). However, the conical-shaped papillae in desert hedgehogs undergo numerous processes and this feature is unique and has not been described before.…”

“…While the lingual root was devoid of the fungiform type, similar observations were recorded in the long‐eared hedgehog (Parchami et al, 2018). Similar papillary arrangements were reported in rabbits even though they are herbivores (Beraldo‐Massoli et al, 2013). The spatial distribution of fungiform papillae varies among mammalian species.…”

The present work attempted to provide a comprehensive description of the morphoanatomical, histological, and ultrastructural characteristics of the tongue in the desert hedgehog (Paraechinus aethiopicus), and to correlate lingual modifications to the feeding lifestyle. Five adult male hedgehogs were utilized in our investigation. The macroscopic observations revealed elongated, with a moderately pointed apex, tongue and the tongue dorsum lacks both lingual prominence and median sulcus. The main subdivisions of the tongue are radix linguae (root), corpus linguae (body), and apex linguae (apex). The tongue dorsum carries two types of mechanical (conical and filiform) and gustatory (fungiform and circumvallate) papillae. The lingual apex is characterized by the existence of a unique encapsulated muscular structure. Additionally, the lingual glands were interposed between the muscular strands and no lingual glands were detected on the lingual apex. The dorsal surface of the lingual apex exhibited the highest level of keratinization as revealed by histochemical staining while the root showed moderate staining. The topography of the tongue was investigated by scanning electron microscopy (SEM). The obtained results are important to provide basic knowledge that can contribute to better understanding of the nourishment, feeding habits and behavior in this species. Furthermore, the addition of the newly investigated species may help us to determine the evolutionary relationships among species.
