“…The histological results demonstrated that the epithelial mucosa layer was composed of squamous epithelium with various degrees of keratinization. The filiform papillae had a thick epithelial layer with numerous cell nuclei and were similar to bharal, 18 goat, 24 tayra, 2 roan antelope, 30 and capybara. 31 The three-dimensional analysis revealed that the filiform papillae were elongated and conical in shape, located in the rostral and middle regions of the tongue, and CTCs had conical shapes.…”

“…1,32,33 The morphologies of the filiform papillae can be subclassified into the following subtypes: two (insectivorous bat); 23 three (fruit bat); 21,23 four (New Zealand white rabbits); 34 or six (fruit bats). 34 The CTC of filiform papillae of the wild boar resembles a conical shape described for the leopard, 16 however, it differs from the U-shape, 35 projections that are finger-like and triangular shape, 36 from CTC formed by main and secondary processes and by multiple processes, 18 and from the CTCs divergent according to the region of the tongue. 25…”

“…3 The development and evolution of the tongue and the lingual papillae can be influenced by their habitat and their functional aspects. 2,4 The tongue and lingual papillae demonstrate wide structural and ultrastructural characteristics among mammals, such as those described for rodents, [5][6][7][8][9][10] equines and ruminants, [11][12][13] canines, 14 sloth, 15 Carnivora order, 1,2,16,17 , Artioctyla order, 18 lesser hedgehog tenrec, 19 rabbit, 20 and bats. 21 The lingual mucosa has a highly differentiated system of papillae, with mechanical and gustatory functions, and those mucosa changes in epithelial morphology between the species are related to the type of food and adaptation of the animal to environmental conditions.…”

The present study aimed to describe the structural and ultrastructural morphological characteristics of the lingual epithelium and the connective tissue cores (CTCs) of wild boar (Sus scrofa). The tongues were processed for light microscopy, scanning electron microscopy, and transmission electron microscopy. In this study, we revealed the filiform, fungiform, foliate, and vallate papillae. The filiform papilla is elongated with a conical shape and its CTC has a conical shape; the fungiform papilla is rounded with a dome-shape and its CTC is flower bud; the foliate papilla is formed by four pairs of epithelial folds and irregular grooves, and its CTC is thin with adjacent conjunctive projections, and taste buds and serous glands in the epithelial layer have been evidenced; and the vallate papilla is oval surrounded by a groove with increases of epithelium surface, and the CTC is formed by numerous connective projections lined. Also noted were serous gland and taste buds on the medial wall of the vallate papilla. The epithelium has the keratinized, granular, spinous, basal, and lamina propria layers. In conclusion, we found new descriptions and shapes of the CTCs of the lingual papillae. In addition, we demonstrated the epithelium structural characteristics, the nuclear distribution between the epithelial layers, and the ultrastructural aspects of the dorsal epithelium of the tongue.

“…Many representatives of Artiodactyla [35][36][37][38][39][40][41][42][43][44][45][46][47][48] have a lingual prominence, which was also observed in the lowland tapir. The main difference in this prominence between animals from the two orders is the presence of much larger conical or lenticular papillae in the Artiodactyla [35,38,46] which are absent in the lowland tapir (apart from conical papillae within the root of the tongue).…”

“…The most discernable pigmentation in the lowland tapir was on the surface of the root of tongue. Another feature of the Artiodactyla [35][36][37][38][40][41][42][43][44][45][46] is a lack of foliate papillae. These were well developed in the lowland tapir.…”

Although the anatomy of the gastrointestinal tract has been characterized in the lowland tapir (Tapirus terrestris), the exact anatomy of its tongue has not been studied. Samples of the lingual papillae and lingual glands were collected from the tongue of an adult female lowland tapir. The microscopic analysis of the structure of the lingual papillae and the histochemical analysis of the secretion of the lingual glands were analyzed. The tongue of the tapir is divided into the apex, body with a distinct lingual prominence, and the root. Its ventral surface is smooth. The most numerous of the mechanical papillae were the filiform papillae, while numerous conical papillae with a sharp apex or more rounded papillae were present in the root of the tongue. There were also nine vallate papillae and pair of foliate papillae. The foliate papillae contained several folds parted by 12–14 grooves. The mucous secretion produced by the lingual glands was more obvious than the serous secretion. The features of the dorsal surface of the tongue as well as the shape and number of the lingual papillae on the surface of the tongue of the examined female tapir differ compared to Equidae or Rhinocerotidae, the other two representatives of Perissodactyla. However, further study is necessary for the synapomorpy of the tapir’s tongue.

The aim of this study was to describe the morphology of the tongue of the okapi, and to compare the results with other ruminants including browsers, intermediates and grazers. The material was collected post‐mortem from two animals from a Zoological Garden. The structure of the okapi tongue, focusing of the shape of the tongue, lingual surface, its papillae and lingual glands, was examined using gross morphology, light and polarized microscopy, and by scanning electron microscopy. The okapi tongue was characterized by dark pigmentation on the lingual dorsum (except lingual torus) and on the whole ventral surface. Two types of filiform papillae were observed, with additional, even 6–8 projections at their base. The round fungiform papillae were present at a higher density, up to 16/cm2, on the ventro‐lateral area of the lingual apex. Round and elongate vallate papillae were arranged in two parallel lines between the body and root of the tongue. Numerous taste buds were detected within the epithelium of their vallum, while fungiform papillae had sparse taste buds. A lack of foliate papillae was noted. Very small conical papillae, some lenticular in shape, were present on the lingual torus. Thick collagen type I fibers were dominant over collagen type III fibers in the connective tissue of the lingual papillae. The mucous acini units were dominant among lingual glands, indicating that the secretion of okapi lingual glands was mostly mucous. In many aspects, the tongue of okapi resembles the tongue of other ruminants. The specific lingual shape and lingual surface, together with the lingual glands, support the processing of plant food, such as young and soft leaves. Although okapi tongue is characterized by smaller conical papillae compared to other ruminants, its high number of vallate papillae is similar that found in other browsers, intermediate and grazers. Thus the number of gustatory papillae rather indicates that this feature is not related to the type of feeding.
