Abstract

Introduction: The lingual papillae have a distinct characteristic structure on the tongue of ma mmalian species, . Generally, there are four types of lingual papillae in ma mmalian species; filiform, fungiform, foliate and vallate. Notably herbivorous animals have filiform, fungiform and vallate, but lacks foliate papillae. Materials and Methods: This study was carried out on the tongues of 12 a healthy adult domestic New Zealand White rabbits of both sexes. Results: The anterior part contains the lingual apex rostrally and makes up almost 2/5 of the tongue length. There were four types of the lingual papilla; one mechanical (filiform) and three gustatory (fungiform, foliate and circumvallate). There were four subtypes of filiform papillae;spoonful conical, processed, leaf-like and triangular filiform papillae. Fungiform papillae were distributed by high number among the spoonful conical filiform papillae on the anterior part of the tongue. The two oval-shape foliate papillae were located on each side of the postero-lateral margin of the lingual prominence, slightly anterior to the circumvallate papillae. The two circumvallate papillae were located behind the lingual prominence and at the root of the tongue. Conclusion: the lingual papillae of rabbit tongue was adapted to its feeding habits according to shape, size, number, nomenclature, orientation and distribution.
