    Filiform papillae are found in large numbers across the tongue’s surface. They are cone-shaped structures that don’t contain taste buds, so have no taste function. Each papilla has brush-like structures called secondary papillae projecting from its tip. They are abrasive giving the tongue a cleaning, rasping action and helping grip food.

    Filiform papillae give the tongue a velvety or furry appearance.
