Scanning electron micrographs—filiform and fungiform papillae of rats. (a) Conical filiform (arrows) and (b) after maceration with NaOH the CTCs of the filiform papillae presented conical (arrows) and bundles (∗) in the interpapillary zone. (c) Multifilamentary papillae (arrows) and (d) their CTCs revealed three to four filaments (arrows) in the third upper part. (e) The fungiform papillae (arrow) exhibited dome-like shape between conical filiform papillae and the highlighted taste orifice (arrowhead) may be seen in the surface. (f) After the removal of the epithelium, the CTCs of the fungiform papillae revealed volcano-like shape, with a cavity on the top for the taste buds (arrow). Bars: 30 μm (a, b, f), 100 μm (c, e), and 10 μm (d).
