types of lingual papillae
There are four types of lingual papillae on the human tongue: circumvallate papillae (vallate papillae), fungiform papillae, filiform papillae and foliate papillae. All except the filiform papillae are associated with taste buds.nlike the other kinds of papillae, filiform papillae do not contain taste buds. They cover most of the front two thirds of the tongue's surface. They appear as very small, conical or cylindrical surface projections, and are arranged in rows which lie parallel to the sulcus terminalis.
