[Light and scanning electron microscopical studies of the soft palate and the tongue in Bombina variegata L (author's transl)].

The soft palate and the tongue of adult Bombina variegata L. were studied by means of light and scanning electron microscopy. In the palate numerous taste-disks were found prominent by their polygonal surface structures. These are caused by longer microvilli at the margins of the different cells of the taste-disk or by deepened margins of the polygonal cells. The surfaces of the cells are slightly convex and are covered by numerous microvilli. In the tongue primarily fungiform papillae were observed (with the exception of the margins were taste-disks similar to those found in the palate were present). Their taste-disks also present polygonal structures, their epithelial cells are characterized by microridges while those of the epithelial folds surrounding the fungiform papillae own microvilli. As special formations within the taste-disks small knob-like protrusions between polygonal cells were found.
