The dorsal surface of the tongue of Zaedyus pichiy (Desmarest, 1804) was examined by scanning electron microscopy. Conical and branched filiform, fungiform and vallate papillae are described. No foliate papillae were seen. Conical filiform papillae are distributed in the apex, both lateral edges and caudally to the vallated ones. The branched papillae represent the most numerous type of lingual...

In the present investigation, the histological and histochemical characteristics, as well as the ultrastructure of the lingual epithelium of the adult lizard Chalcides ocellatus, were investigated by light microscopy (LM) and scanning electron microscopy (SEM). Histological examination revealed taste buds and sensory papillae on the tongue tip and on the foretongue. The papillae were covered by...

The microstructure of lingual papillae on the dorsal surface of the tongue of adult Egyptian fruit bats was examined by light microscopy (LM) and scanning electron microscopy (SEM). This elongated tongue with a rounded apex is approximately 3 cm long -- including the 1.7cm length of the anterior free part of the tongue -- which facilitates considerable freedom of movement. The surface of the to...

The filiform papillae were smallest in size and the most numerous of all lingual papillae which distributed on dorsal surface, ventral surface and rarely extend caudally at level of circumvallate papillae. Filiform papillae which found on lateral margin and at tip of tongue were highly cornified. Fungiform papillae were distributed among filiform papillae and are more concentrated around the ti...

The tongue surface directly above a fungiform taste bud is flat, thinly keratinized, and free of filiform spines. We examined fungiform papillae in serial sections of rat and gerbil tongues after unilateral transection of the chorda-lingual nerve had caused many fungiform taste buds to degenerate. Such empty fungiform papillae often formed a solitary keratinized outgrowth that closely resembled...

The dorsal lingual papillae of the lesser mouse deer were studied morphologically using light and scanning electron microscopy. Four types of papillae, filiform, fungiform, vallate and foliate, were observed. Filiform papillae consisted of larger main papillae with smaller secondary papillae on their anterolateral aspects. Secondary papillae were well distributed over the anterior two-thirds of...

BACKGROUND: The tongue, which plays a very important role in food intake by vertebrates, exhibits significant morphological variations that appear to represent adaptation to the current environmental conditions of each respective habitat. OBJECTIVES: The aim of the present investigation was to investigate lingual structure in adult budgerigar. METHODS: Tongues of 12 adult budgerigars were used ...

The dorsal lingual surfaces of two adult Japanese marten (Martes melampus) were examined by scanning electron microscopy (SEM). Filiform, fungiform, vallate and foliate papillae were observed. A small filiform papilla on the apical surface of the tongue had several pointed processes. A small filiform papilla contained the connective tissue core consisting of several small processes. A large fil...

BACKGROUND Pain and sensory changes due to lingual nerve injury are one of the most common alterations that follow surgical removal of third molar. They are usually transient but other less common complications, such as the atrophy of fungiform papillae, have an uncertain prognosis. CASE DESCRIPTION We report a case of a 34-year-old woman who presented a unilateral lingual atrophy of fungifor...

There have been few studies of lingual morphology and associated papillae of rodents since a 1924 study restricted mostly to Old World taxa (1). This is especially applicable to the North American superfamily Geomyoidea. We examined the distribution patterns and types of lingual papillae for three geomyids and 12 heteromyid rodent species. All member taxa have a single circunivallate papilla, w...
