The morphological characteristics of bovine and equine gustatory lingual papillae are compared by scanning electron microscopy. The fungiform papillae in the cow have a shape that corresponds to their name, while in the horse, they almost do not emerge from the surface of the tongue. These papillae show taste pores in both species. The vallate papillae, four times larger in the horse than in the cow, show a complex organization of papillae and secondary grooves in the horse. In the cow, they occur single and are surrounded by a thick annular pad of lingual mucosa. Taste pores have been observed in the vallate papillae of both species, whereas in the foliate papillae, they are present only in the horse. A characteristic distribution of stratified scales and channeled tracts is observed on the surface of all gustatory papillae in both species. The possible functional importance of each type of gustatory papilla is discussed on the basis of their morphostructural features.
通过扫描电子显微镜比较牛和马的味觉舌乳头的形态特征。奶牛的菌状乳头形状与其名称相符，而在马中，它们几乎不从舌表面突出。这两种动物的这些乳头都有 taste 孔。马的轮廓乳头比奶牛的大四倍，在马中显示出乳头和次级沟的复杂结构。在奶牛中，它们单个出现，并被厚厚的舌粘膜环形垫包围。在这两种动物的轮廓乳头中都观察到了 taste 孔，而在叶状乳头中，它们只存在于马中。在这两种动物的所有味觉乳头表面都观察到分层鳞片和通道束的特征分布。根据它们的形态结构特征讨论了每种味觉乳头可能的功能重要性。
