Abstract: The morphology of the dorsal lingual papillae of the adult Goitered gazelle was examined by scanning electron microscopy and light microscopy. On the dorsal surface of the lingual mucosa, three types of mechanical papillae and two types of gustatory papillae were observed. Numerous filiform papillae covered the entire surface of the lingual apex and body except for the lingual torus of the dorsal lingual surface. The structure and size of filiform papillae vary in the apex and body parts of the tongue. Two types of lenticular papillae were observed including rounded type papillae in the anterior median portion and half-cut pyramid shaped papillae in the posterior median portion of the lingual torus. Conical papillae were distributed on all parts of the lingual torus excluding the median plane and were also observed on the root of the tongue. Fungiform papillae, dispersed the lingual apex and body and the lateral sides of the lingual torus, display regional variation in structure and size. The smaller papillae on the lingual apex and body were mainly located along the sides of the tongue among filiform papillae while the larger papillae on the lateral and posterior parts of the lingual torus were located among conical papillae and had a convex surface. Large fungiform papillae lacked taste buds. The number of vallate papillae was 26 in the caudolateral region of the lingual torus. These papillae were observed to have a compact structure and to possess shallow grooves. No foliate papillae were seen on the dorsal surface.
