C. Utiyama et al., SCANNING ELECTRON-MICROSCOPIC STUDY OF THE DORSAL SURFACE OF THE TONGUE OF CALOMYS CALLOSUS MOUSE, Annals of anatomy, 177(6), 1995, pp. 569-572
The characteristics of the dorsal mucosal surface of Calomys callosus'
tongue were studied employing scanning electron microscopy. The sampl
es were fixed with modified Karnovsky solution, and postfixed in 1% Os
O4, followed by dehydration and critical point drying. The scanning el
ectron microscopy gives a three dimensional image of the filiform, fun
giform, vallate and foliate papillae. The filiform papillae were found
on the anterior tip and dorsal surface; the fungiform papillae on the
dorsal and anterior surfaces; only one vallate papilla, elongated in
shape, is located in the posterior third, and the small foliate papill
ae were to be seen in the posterolateral region of the tongue.
