SEM Study on the Dorsal Lingual Surface of Microtus Montebelli

Abstract

The dorsal lingual surface of Microtus montebelli was examined by scanning electron microscopy (SEM). The filiform papillae were distributed over the entire dorsal surface of the tongue. The filiform papillae notably differed in morphology by their location on the tongue and could be classified into 4 types: 1) simple conical papillae, 2) true filiform papillae, 3) giant conical papillae, and 4) saw-like papillae. The fugiform papillae were present rounded bodies scattered over the anterior dorsal surface of the tongue. A vallate papilla was located at the middle end of the lingual body. The surface of the radix zone was smooth and without lingual papillae.

Light and scanning electron microscopy of the tongue of a degu (Octodon degus)

“…Unlike the agouti (Ciena et al 2013), capybara , nutria (Emura et al 2001), large vesper mouse (Watanabe et al 1997), Japanese dormouse (Kubota and Togawa 1966) and American beaver (Shindo et al 2006), where filiform, fungiform, foliate and vallate papillae were described, the dorsal lingual surface of the tongue in a degu bore filiform, conical and vallate papillae. Three types of the lingual papillae were reported also in the Middle East blind mole rat (Kilinc et al 2010).…”

“…Filiform, fungiform, vallate and foliate papillae have been found in the agouti, Dasyprocta aguti (Ciena et al 2013), capybara, Hydrochaeris hydrochaeris , American beaver, Castor canadensis (Shindo et al 2006), nutria, Myocastor coypus (Emura et al 2001), large vesper mouse, Calomys callosus (Watanabe et al 1997), porcupine, Hystrix cristata ) and Japanese dormouse, Glirus japonicus (Kubota and Togawa 1966). Foliate papillae were absent in the Middle East blind mole rat, Spalax ehrenbergi (Kilinc et al 2010), Japanese grass vole, Microtus montebelli (Emura et al 1999) and squirrel, Sciurus vulgaris (Unsaldi 2010). Vallate papillae have not been revealed in the tongue of the guinea pig, Cavia porcellus (Sakr et al 2013).…”

“…Scanning electron microscopic studies of the tongue have already been performed on agouti, Dasyprocta aguti (Ciena et al 2013), capybara, Hydrochaeris hydrochaeris , Patagonian cavy, Dolichotis patagonum (Emura et al 2011), nutria, Myocastor coypus (Emura et al 2001), large vesper mouse, Calomys callosus (Watanabe et al 1997), porcupine, Hystrix cristata (Atalar and Karan 2011), Middle East blind mole rat, Spalax ehrenbergi (Kilinc et al 2010), house-mouse, Mus musculus (Kobayashi et al 1989), Manchurian chipmunk, Tamias sibiricus (Kobayashi et al 1992), Japanese grass vole, Microtus montebelli (Emura et al 1999), guinea pig, Cavia porcellus (Sakr et al 2013), American beaver, Castor canadensis (Shindo et al 2006), hazel dormouse, Muscardinus avellanarius (Wolczuk 2014).…”

Morphology of the lingual papillae in the Egyptian rousette bat (Rousettus aegyptiacus)

“…There was a single vallate papilla on the tongue of the squirrel monkey (Iwasaki et al, 1988). There were two vallate papillae in the Japanese longfingered bat and nutria (Kobayashi and Shimamura, 1982;Emura et al, 2001b) while the long-nosed bat had four (Greenbaum and Philips, 1974). On the tongue of the bush dog, Emura et al (2000c) observed five vallate papillae.…”

SEM Study on the Dorsal Lingual Surface of the Lesser Dog-Faced Fruit Bat, Cynopterus brachyotis

“…In many animals, the Fu are scattered almost uniformly among the Fi, mainly on the anterior part of the lingual body (Emura et al, 1999a(Emura et al, , b, c, 2000a. In this study, the Fu are scattered among the Fi on the anterior 2/3, exepted for the midportion of the anterior 1/3 of the tongue.…”
