I. Watanabe et al., SCANNING ELECTRON-MICROSCOPY STUDY OF THE INTERFACE EPITHELIUM-CONNECTIVE TISSUE SURFACE OF THE LINGUAL MUCOSA IN CALOMYS CALLOSUS, ANNALS OF ANATOMY-ANATOMISCHER ANZEIGER, 179(1), 1997, pp. 45-48
The characteristics of the interface epithelium-connective tissue of t
he lingual mucosa of Calomys callosus was studied by employing scannin
g electron microscopy after removal of the epithelial cells. In the an
terior part, the connective tissue papillae of filiform papillae are d
istributed at random in their original configuration, and the round-sh
aped fungiform papillae are scattered among the filiform papillae. In
the middle part, the filiform papillae present several rod-shaped proj
ections. In the posterior part, the vallate papilla are oval in shape,
and the connective tissue reveals a large ridge separated by deep lat
eral grooves. The posterior adjacent area is a flat surface and shows
several openings of salivary gland ducts. The foliate papillae are for
med by several small ridges separated by grooves. In the areas adjacen
t to the foliate papilla, small pointed and laminar papillae were obse
rved.
