Caption: False-colour scanning electron micrograph of part of a filiform papilla emerging from the tongue's surface. It is partly covered by green coloured bacteria. Filiform papillae, also known as conical papillae, are covered by stratified squamous epithelial cells apart from their tips, which are formed by the fibrous protein keratin in order to increase the papillae's strength. The image clearly shows the intricate pattern of microfolds on the cell surfaces. Filiform papillae have mechanical and tactile functions and form a rough surface which helps mastication. Magnification: x5290 at 6x7cm size. Magnification: x8050 at 4x5 inch size.
