Let us look at each of the four types of papillae in detail explaining their location, shape and histology in detail. Filiform papillae: These are the most numerous papillae seen on the surface of the tongue and are hair like or thread like in appearance projecting out from the dorsal surface of the tongue and are seen on the front two thirds of the tongue. Filiform papillae do not contain Taste Buds in them.
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.n some diseases, there can be depapillation of the tongue, where the lingual papillae are lost, leaving a smooth, red and possibly sore area. Examples of depapillating oral conditions include geographic tongue, median rhomboid glossitis and other types of glossitis.
