Lingual papilla

From Wikipedia, the free encyclopedia

Lingual papillae (singular papilla) are small nipple hair like structures on the dorsum of the tongue, giving it a rough texture. There are four types of lingual papillae in humans: circumvallate papillae (vallate papillae), fungiform papillae, filiform papillae and foliate papillae. All except the filiform papillae are associated with taste buds.[1]

In 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.
