摘要
Anatomically the tongue of Gallus gallus domesticus (Galliformes: Phasianidae) is distinguished into sharp rostral apex, body and root with numerous conical papillae arranged in rows in different sizes in the free portion and the root of the tongue. The epithelium covered the dorsal and ventral surfaces of the free portion and the dorsal surface of the root of the tongue. Numerous orifices of the salivary glands were scattered in the root of the tongue. SEM investigation of the connective tissue cores after maceration of the tongue in 10% NaOH showed the presence of thread-like structures of the connective tissue cores in the rostral apex of the tongue, rod-shaped protrusions in the middle of the free portion and ring-like process posteriorly, while in the conical papillae, they appeared like thin parallel striations. The connective tissue core formed sheaths around the orifices of the salivary glands. While the connective tissue cores of the laryngeal area showed saw-shaped protrusions. Ventrally, the connective tissue core of the lingual nail was arranged in longitudinal parallel rows. SEM investigation revealed that the connective tissue core of the epithelium covered the tongue and closely conformed to the form and size of the filiform papillae.
