Mammal tongue papillae (cat). Papillae project toward the back of the tongue. They form backward-facing hooks which help hold food and provide the abrasiveness needed for self-grooming. They do not have taste buds. The taste buds are carried by mushroom-shaped papillae at the tip and sides and the cup-shaped papillae at the back of the tongue.
