The upper surface of the tongue is covered in [[oral mucosa#Classification|masticatory mucosa]], a type of [[oral mucosa]], which is of [[oral mucosa#Types|keratinized stratified squamous epithelium]]. Embedded in this are numerous [[lingual papilla|papillae]], some of which house the [[taste bud]]s and their [[taste receptor]]s.<ref>{{cite web|title=taste bud anatomy|url=http://www.britannica.com/science/taste-bud|website=Encyclopædia Britannica | first1 = Elizabeth | last1 = Bernays | first2 = Reginald | last2 = Chapman }}</ref> The lingual papillae consist of [[filiform papillae|filiform]], [[fungiform papillae|fungiform]], [[vallate papillae|vallate]] and [[foliate papillae]],<ref name=GRAYS2005 /> and only the filiform papillae are not associated with any taste buds.

The tongue can divide itself in dorsal and ventral surface. The dorsal surface is a stratified squamous keratinized epithelium, which is characterized by numerous mucosal projections called papillae.<ref>{{cite book|last1=Fiore|first1=Mariano|last2=Eroschenko|first2=Victor|title=Di Fiore's atlas of histology with functional correlations|date=2000|publisher=Lippincott Williams & Wilkins|pages=238|url=http://www.almustafauniversity.com/wp-content/uploads/2016/04/difiores-atlas-of-histology-with-functional-correlations-11th-ed.pdf |url-status=dead |archive-url=https://web.archive.org/web/20170621161523/http://www.almustafauniversity.com/wp-content/uploads/2016/04/difiores-atlas-of-histology-with-functional-correlations-11th-ed.pdf |archive-date=21 June 2017}}</ref> The lingual papillae covers the dorsal side of the tongue towards the front of the terminal groove. The ventral surface is stratified squamous non-keratinized epithelium which is smooth.<ref>{{cite book|last1=Hib|first1=José|title=Histología de Di Fiore: texto y atlas|url=https://archive.org/details/histologiadedifi00hibj|url-access=limited|date=2001|publisher=El Ateneo|location=Buenos Aires|isbn=950-02-0386-3|page=[https://archive.org/details/histologiadedifi00hibj/page/n196 189]}}</ref>
