Papillae of tongue
You have four different types of taste buds, including: Filiform. Located on the front two-thirds of your tongue, filiform papillae are thread-like in appearance. Unlike other types of papillae, filiform papillae don’t contain taste buds. Fungiform. These papillae get their name from their mushroom-like shape. Located mostly on the sides and tip of your tongue, fungiform papillae consist of approximately 1,600 taste buds. Circumvallate. The small bumps on the back of your tongue are the circumvallate papillae. They appear larger than the other types of papillae, and they contain approximately 250 taste buds. Foliate. Located on each side of the back portion of your tongue, the foliate papillae look like rough folds of tissue. Each person has about 20 foliate papillae, which contain several hundred taste buds.
