The Filiform papillae cover the anterior two-thirds of the dorsal surface of the tongue.
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 papillæ these are of a whitish tint, owing to the thickness and density of the epithelium of which they are composed, which has here undergone a peculiar modification, the cells having 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 papillæ of this group are sometimes termed papillae conicae.
