SEM Studies on the Tongues of the Carrion Crow

Abstract

The dorsal lingual surface of carrion crows (Corvus corone) was examined by scanning electron microscopy. Three parts were distinguished on the dorsal surface of the tongue: the apex, the body and the root of the tongue. The conical papillae of the lingual body were inclined toward the posterior of the tongue. The dorsal surface of the lingual apex was the smooth surface of the lingual apex. The connective tissue cores of the epithelium of the lingual apex showed many triangular protrusions. Small and large conical papillae were observed in the lingual body. Many openings of the lingual glands were observed in the lingual root.
