This study was carried out to investigate the morphological development of the tongue in the 60-, 90- and 120-day-old fetuses and neonates of Korean native goats by light microscopy. In 60-day-old fetuses, the tongue tissues were differentiated into epithelium, lamina propria, and muscle layer. The primordia of filiform, conical, lentiform, fungiform, and vallate papillae appeared by this time, and rudiments of taste buds were observed in the epithelia of the primordia gustatory papillae. The dorsal lingual epithelia were PAS positive.
