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.

The aim of this study was to investigate morphological development of filiform papillae (FP) in Korean native goats by using scanning electron microscopy. Tongues were removed from goat fetuses (days 60, 90, and 120), neonates, and juveniles (days 30, 60, 90, 120, 150, and 180 after birth). During the prenatal period, primordia of FP appeared at fetal day 60 and were observed to be developed at day 90. At fetal day 120, the FP were observed like flower leaves of a double flower bud. In neonates, FP were shaped like an obliquely sectioned cylinder with secondary papillae irregularly arranged in a saw blade-like manner. In 60-day-old juvenile goats, the FP were densely distributed at the inner base of 1/3-1/2 degrees. In 90-, 120-, and 150-day-old goats, FP were compacted at the inner base of 1/2-2/3, 3/4, and 4/5 degrees, respectively. In 180-day-old goats, FP were found to be completely compacted on the inner surface with complete morphogenesis. Microridges, microplicae, and micropits were well-developed on the epithelial surface of lingual papillae from embryonic day 120 to juvenile day 180. These results indicate that FP of goats have different shapes and sizes during development both before and after birth.
