“…Th e fungiform papillae in guinea pig (Kobayashi, 1990), goat (Kurtul, Atalgin, 2008), Persian squirrel (Goodarzi, 2014) and maned sloth (Benetti et al, 2009) are reported to be concentrated on the lingual apex and also on both lateral borders. However, fungiform papillae in the common shrew are restricted to the lingual corpus (Jackowiak et al, 2004). Nasr (2012) reported that fungiform papillae of Erinaceous auritus are populated on the apex of the tongue and form clusters of two or three papillae.…”

“…Many studies in various mammalian species indicate that there is a wide variability in morphological features of lingual papillae and a close correlation between lingual papillae structure, feeding habits and taxonomy (Jackowiak, Godinicki, 2005). Although, this variability is remarkable between high systemic units, such as orders and families, interspecies diff erences are also seen frequently (Iwasaki, 2002;Kobayashi et al, 2005;Emura et al, 2006;Jackowiak et al, 2004).…”

The morphology and histological structure of two adult Brandt’s hedgehog, Paraechinus hypomelas, (Brandt, 1836) tongue were examined by light and scanning electron microscopy. On the dorsal surface of the tongue, three types of papillae were observed: filiform, fungiform and vallate papillae. Apex and corpus of the tongue as well as the lateral surface of the corpus were covered with numerous filiform papillae with bifurcated tip, while the epithelium lining the ventral lingual surface was free from papillae. Discoid shape fungiform papillae were scattered over the entire surface of the lingual apex, corpus and lateral surface uniformly between the filiform ones without regional variation in number and size. Three elliptical or oval vallate papillae in an inverted triangle form were found on the root of the tongue. Each papilla had a lobulated and very irregular dorsal surface. Both fungiform and vallate papillae contain taste buds. The foliate papillae was absent. Overall, the present findings reveal that despite some similarities, the lingual papillae of the Brandt’s hedgehog as an omnivore animal has spices-specific characteristics compare to the Erinaceous auritus as an insectivore species. This finding provides a set of basic data about the morphology of tongue and its lingual papillae in Brandt’s hedgehog.

We examined the epithelial surface and connective tissue cores (CTCs) of each lingual papilla on the Paenungulata, Cape hyrax ( Procavia capensis ), by scanning electron microscopy and light microscopy. The tongue consisted of a lingual apex, lingual body and lingual root. Filiform, fungiform and foliate papillae were observed on the dorsal surface of the tongue; however, fungiform papillae were quite diminished on the lingual prominence. Moreover, no clearly distinguishable vallate papillae were found on the tongue. Instead of vallate papillae, numerous domelike large fungiform papillae were arranged in a row just in front of the rather large foliate papillae. Foliate papillae were situated in the one-third postero-lateral margin of the lingual body. The epithelium of filiform papillae was covered by a keratinized layer with kerato-hyaline granules, whereas weak keratinization was observed on the interpapillary epithelium. The external surface of the filiform papillae was conical in shape. CTCs of the filiform papillae were seen as a hood-like core with a semicircular concavity in the anterior portion of each core. Large filiform papillae were distributed on the lingual prominence. The CTCs of large filiform papillae after exfoliation of their epithelium consisted of a concave primary core and were associated with several small protrusions. The surface of fungiform papillae was smooth and dome-like. After removal of the epithelium, CTCs appeared as a flower bud-like primary core and were associated with several protrusions that were arranged on the rim of the primary core. Several taste buds were found on the top of the dorsal part of the epithelium of both fungiform and large fungiform papillae. Well-developed foliate papillae were seen and numerous taste buds could be observed in the lateral wall of the epithelium in a slit-like groove. The morphological characteristics of the tongue of the Cape hyrax had similarities with other Paenungulata such as Sirenia. However, three-dimensional characteristics, especially CTCs of lingual papillae, exhibited multiple similarities with rodents, insectivores and artiodactyls.

“…Many studies have demonstrated morphological diversity among the oral tissues of mammals (Nickel et al., ), particularly with respect to the three‐dimensional structure of the papillae linguales and their connective tissue cores (CTCs) in terrestrial species (Kobayashi et al., , ; Kobayashi, ; Adnyane et al., ; Watanabe et al., ). Following the early macroscopic studies of insectivores by Sonntag (), there have been several detailed morphological investigations into the papillae linguales of the Soricomorpha, for example, Talpidae such as Mogera (Kobayashi et al., ; Miyata et al., ), Talpa (Jackowiak, ) and Dymecodon (Kobayashi et al., ); and Soricidae including Solex , (Kobayashi and Iwasaki, ; Jackowiak et al., ), Suncus (Kobayashi et al., ; Kobayashi and Iwasaki, ), Chimarrogale (Kobayashi and Iwasaki, ) and Crocidura (Kobayashi (), Kobayashi et al. (, ).…”

The external morphology of the papillae linguales (papillae filiformes, papillae fungiformes and papillae vallatae) and their connective tissue cores (CTCs) of the greater Japanese shrew-mole (Urotrichus talpoides) were analysed by optical and scanning electron microscopy. Papillae filiformes were distributed over the dorsal surface of the apex linguae, and on the rostral and caudal regions of the corpus linguae but were less numerous in the mid-region. They were absent from the radix linguae. A pair of oval papillae vallatae was situated at the border between the corpus linguae and the radix linguae. Papillae foliatae were absent. The epithelial surface of each papilla filiformis consisted of a circular concavity, a ring-like wall and either a single thumb-like process or 2–3 slender pointed processes, depending on their location. The morphology of the CTCs of the papillae filiformes also varied regionally. The papillae linguales of the Japanese shrew-mole were morphologically similar to those of other Talpidae and Soricidae, including the common shrew, particularly with respect to the papillae filiformes in the mid- and caudal regions of the corpus linguae.
