“…Other authors have actually attempted to remove cellular elements to expose the connective tissues, using acetic acid (HORSTMANN, 1952, 1954, 1957), trypsin (SCHENK and WERSALL, 1975, EDTA (KLEIN-SZANTO and SCHROEDER, 1977), prolonged fixation in 0504 followed by ultrasonication (HIGHISON and Low, 1982), maceration in boric acid plus ultrasonication (Low and MCCLUGAGE, 1984), washing in a jet of Ringer's solution (MIYOSHI and SHINGU, 1984), or with low temperature HCl (KOBAYASHI, MIYATA and IINO, 1987). Our experiments, however, have revealed that treatment with NaOH at room temperature is able to remove cellular elements much more effectively and consistently, and thus more clearly expose the connective tissue fibers than any other methods so far reported.…”

“…Main protrusion of filiform CTCs were found on the posterior part of each central concavity. Regarding the lingual papillae of the dog tongue (Kobayashi et al, 1987(Kobayashi et al, , 1988b(Kobayashi et al, ,c, 1992, the CTCs of the filiform papillae also exhibited central concavities and main protrusions that were situated at posterior part of each CTC. These structural characteristics of each fungiform and filiform CTCs exhibited similarity with present observations.…”

“…filiform, fungiform, vallate and foliate papillae depending on species. Furthermore, regarding three-dimensional morphological structure of the lingual papillae and their connective tissue cores (CTCs) after exfoliation of the epithelium, there are many differences originating in part from the various dietary habits of carnivorous, omnivorous and herbivorous land mammalian species (Kobayashi et al, 1987; Kobayashi and Iwasaki, 1988Iwasaki, , 1989.…”

Summary: We observed the external surface and connective tissue cores (CTCs) of the lingual papillae (filiform, fungiform and vallate papillae) of adult Spotted seals (Phoca largha) using SEM and light microscopy. The tongue was Vshaped and its apex was rather rounded. On the dorsal surface from apex to the one-third posterior of the tongue, the lingual mucosa was densely covered by filiform papillae, with a scatted distribution of dome-like fungiform papillae, which have orthokeratinized epithelium. At the posterior part of the tongue, filiform papillae were totally diminished and their epithelium was parakeratinized. Approximately 6-7 vallate papillae were arranged in a V-shape on the posterior of the tongue. After removal of the epithelium, the CTCs of the filiform papillae that were distributed at apex consisted of a primary core and approximately 5-6 rod-shaped small accessory cores. The CTCs of filiform papillae that were distributed at anterior part of the tongue lacked primary protrusions and possessed approximately 10-15 rod shaped small accessory cores that were arranged in a horseshoe manner. The CTCs of fungiform papillae had cylindrical primary cores and were fringed with accessory protrusion. In the Vallate papillae, taste buds were only seen at the dorsal epithelium.

“…In the order Carnivora, there have been many SEM studies of the tongues of cat (Boshell et al, 1982;Kobayashi et al, 1988), dog (Iwasaki and Sakata, 1985; Kobayashi et al, 1987), mongoose (Iwasaki et al, 1987), Japanese weasel (Furubayashi et al, 1989), sea otter (Shimoda et al, 1996), Asian black bear (Inatomi and Kobayashi, 1999), bush dog (Emura et al, 2000), panther and Asian black bear (Emura et al, 2001), lion (Emura et al, 2003), tiger (Emura et al, 2004), silver fox (Jackowiak and Godynicki, 2004) and raccoon dog and fox (Emura et al, 2006). Such studies reveal variations in morphology and distribution of papillae on the dorsal lingual surface among animal species.…”

Summary: 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 filiform papilla of the lingual body consisted of a main papilla and some secondary papillae. A large filiform papilla contained the connective tissue core consisting of processes of various size. The fungiform papillae are round in shape. The connective tissue core of the fungiform papilla had a top with several round depressions. The four vallate papillae were located on both sides of the posterior end of the lingual body and each papilla was surrounded by groove and crescent pad. A zigzag surface structure appeared on the connective tissue core of the vallate papilla. The foliate papillae were seen on the dorsolateral aspect of the tongue and some ridges and grooves were exposed reciprocally. A zigzag surface structures appeared on the connective tissue cores of the ridges of the foliate papillae.
