Dorsum of Adult Tongue
Note the numerous papillae covering the dorsum of the adult tongue. They give the surface a textured appearance. The majority of the tiny projections in this image are filiform papillae (A). Filiform papillae are exposed to constant abrasive action during eating, talking, swallowing, etc. This results in their tips becoming protected by a layer of keratin.
