This image shows the intricate pattern of minute surface projections (papillae). The more numerous are filiform papillae (purple), also known as conical papillae, which have mechanical and tactile (touch) functions. These papillae also form a rough surface which helps in the chewing and manipulation of food. Fungiform papillae (round, red) are less numerous, and are well supplied with blood; they contain taste buds under their surface, thus playing a sensory role.
