Summary: The dorsal lingual surfaces of the raccoon dogs (Nyctereutes procyonoides) and fox (Vulpes vulpes japonica) were examined by scanning electron microscopical (SEM) observations. The distribution and type of the lingual papillae found in the raccoon dog were similar to those in the fox. Filiform, fungiform, foliate and vallate papillae were observed. The filiform papillae were distributed over the entire dosal surface of the tongue. Each filiform papilla on the apical surface of the tongue had several pointed processes. The filiform papillae of the lingual body consisted of a main papilla and some secondary papillae. The fungiform papillae were present rounded bodies, and more densely distributed on the lingual apex. The foliate papillae were seen on the dorsolateral aspect of the tongue. The vallate papillae were located on both sides of the posterior end of the lingual body. Each papilla was surrounded by groove and crescent pad. On the periphery of the papillae, large conical papillae were observed.

“…Three vallate papillae were also found on the tongues of marsupials (Kubota et al, 1963;Krause and Cutts, 1982;Kobayashi et al, 2003;Emura, 2011), primates (Kubota and Hayama, 1964;Emura et al, 2002a), rodents (Kubota and Togawa, 1966;Emura et al, 1999), lagomorphs (Kubota, 1966), insectivores (Chunhabundit et al, 1992) and Chiroptera (Emura et al, 2001;Emura et al, 2002b). In this study, the brush-tailed rat kangaroo showed a triangular arrangement of the three vallate papillae, with the apex of the triangle directed posteriorly.…”

Morphology of the lingual papillae in the brush-tailed rat kangaroo

Summary:We examined the dorsal lingual surface of an adult brush-tailed rat kangaroo (Bettongia penicillata) by scanning electron microscopy. The filiform and fungiform papillae on the lingual apex and body consisted of a main papilla and secondary papillae. The connective tissue core of the filiform papillae on the lingual apex was cylindrical in shape with a crushed top. The connective tissue core of the filiform papillae on the lingual body had one large and several small processes. The fungiform papillae were round in shape. The connective tissue core of the fungiform papillae had several depressions on its top. The surface of the vallate papillae was rough and the papillae were surrounded by a groove and a pad. Several long conical papillae derived from the posterolateral margin of the tongue where foliate papillae have been shown to be distributed in many other animal species. The long conical papillae were very similar to those of the koala and opossum.

“…Several studies have indicated that the vallate papillae were flattened and oval in shape and were surrounded by a groove and a pad (Krause and Emura et al, 2013). The vallate papillae of the cat, dog and flying squirrel were found to be encircled by the filiform papillae in the posterior body (Boshell et al, 1982;Iwasaki and Sakata, 1985;Emura et al, 1999). Equine vallate papillae were composed of a primary papilla that was divided into several secondary papillae by intermediate grooves (Chamorro et al, 1986).…”

Summary:We examined the dorsal lingual surface of an adult fishing cat (Prionailurus viverrinus) by scanning electron microscopy. The filiform papillae on the lingual apex had several pointed processes. The connective tissue core of the filiform papillae resembleda a well in shape. The filiform papillae on the anterior part of the lingual body were large and cylindrical in shape. The connective tissue core of the filiform papillae consisted of a large conical papilla. The filiform papillae on the central part of the lingual body were large and conical. The connective tissue core of the filiform papillae consisted of a large main process and some secondary processes. The connective tissue core of the fungiform papillae did not have processes. The vallate papillae were surrounded by a groove and a pad. The top of the connective tissue core of the vallate papillae had a rough surface with no spines.
