Abstract

The present work was focused on the morphological characters of the lingual caruncles, and tongue with its papillae of Egyptian water buffalo (Bubalus bubalis) using the gross, light, and scanning electron microscope. The ventral surface of the sublingual caruncle carried a small opening of the duct of both monostoamtic and mandibular salivary gland. The lingual mucosa of dorsal, lateral border, some extent to ventral surface of apex had lingual papillae (filiform, fungiform), while the lingual mucosa of body especially at torus linguae had conical papillae, but circumvallate papillae observed at the caudal part of body and root. The dorsal surface of apex and body carried numerous long thread-like with blunt apex caudally directed filiform papillae that covered with keratinized scales without secondary papillae. The degree of keratinization classified filiform papillae into rostral part of high keratinization and caudal less keratinization. Conical papillary surface carried exfoliated epithelium with longitudinal groove on its rostral surface and had CT core does not reach the level surface of epithelium and carried secondary papillae. Fungiform papillae scattered among filiform papillae on the dorsal and ventral surface of apex and its convex surface had exfoliated keratinized epithelium. Circumvallate papillae surrounded by circular deep groove that bordered by vallum that carried small secondary papillae that ended into the primary groove. Taste buds of circumvallate papillae opened in the lateral lining epithelium facing the groove. Von Ebner's glands were observed in CT under papillae especially toward the groove and their ducts open into the base of the groove.
