Structure giving the tongue its characteristic rough texture
Lingual papillae
Lingual papillae (sing.: papilla, from Latin lingua 'tongue') are small structures on the upper surface of the tongue that give it its characteristic rough texture. The four types of papillae on the human tongue have different structures and are accordingly classified as circumvallate (or vallate), fungiform, filiform, and foliate. All except the filiform papillae are associated with taste buds.
