Abstract
|
|
|
|
The aim of this study was to investigate the morphological development of fungiform papillae in native Korean goats by scanning electron microscopy (SEM). Tongues were removed from fetuses on days 120 and 150 of gestation and from juveniles on days 30, 60, 90, 120, 150, and 180 after birth. The sizes of fungiform papillae in the newborn were 225.0-250.0 μm, the weaning period of 60-day-old goats was 271-294 μm and the maturing period of 180-day-old goats was 385-398 μm, respectively. The primordia of fungiform papillae had the typical feature of a mushroom shape in a 120-day-old fetus. In a 150-day-old fetus (neonate), fungiform papillae had features similar to those of the adult form and showed a gradual increase in size with slight morphological changes until 150-day-old goats. Microridges, microplicae, and micropits were well developed on the epithelial surface of lingual papillae from 60 to 150-day-old goats. The results obtained in this study might provide some basic data on the mechanisms that control the morphogenesis and development of the lingual papillae in ruminants.
