Preferred Label : filiform papilla;
Uberon definition : The filiform papillae are thin, long 'V'-shaped cones that don't contain taste buds
but are the most numerous. These papillae are mechanical and not involved in gustation
covering most of the dorsum (upper surface). They are small and arranged in lines
parallel to the V-shaped row of circumvallate papillae, except at the tip of the tongue
where they are aligned transversely. Projecting from their apices are numerous filamentous
processes, or secondary papillae. These are of a whitish tint, owing to the thickness
and density of the epithelium of which they are composed. This epithelium has undergone
a peculiar modification as the cells have become cornified and elongated into dense,
imbricated, brush-like processes. They contain also a number of elastic fibers, which
render them firmer and more elastic than the papillae of mucous membrane generally.
The larger and longer papillae of this group are sometimes termed papillae conicae.
Fungiform papillae are found dispersed throughout the filiform papillae. [WP,unvetted].;
