Papillae are the tiny raised protrusions on the tongue that contain taste buds. The four types of papillae are filiform, fungiform, foliate, and circumvallate. Except for the filiform, these papillae allow us to differentiate between sweet, salty, bitter, sour, and umami (or savory) flavors.
What is the function of papillae of tongue?
