Lingual papillae of wild boar and pig were studied by means of scanning electron microscopy (SEM). Vallate papillae appear with the typical circumvallate morphology. Their papillary bodies show conical or fungiform-like and spicule-like pseudopapillae in both animals. Taste pores were seen in the papillary grooves. Microplicae or pits are visible at high magnification. In pig and wild boar similar foliate papillae were observed. Pig has less but wider leaves than wild boar. Taste pores on papillary walls were viewed. At high magnification microplicae were seen. Morphologically, fungiform papillae correspond with their denomination. Taste pores open onto the upper surface and they are easily identifiable by SEM. The rostral and lateral regions contain the major number of fungiform papillae. The lateral papillae of wild boar and pig show a high number of pores per papilla. These regions must be considered important in taste sensitivity. Lateral papillae in both animals could provide a source of taste buds for study. In both animals the fungiform papillary epithelium showed a pitted appearance as a consequence of keratinization by food environmental stress. The filiform papillae can be both simple and compound (with body and hairs). Large conical papillae are located caudally and curved in the same direction. Filiform and conical papillae have a function in food mastication, handling and deglutition.
通过扫描电子显微镜（SEM）对野猪和家猪的舌乳头进行了研究。轮廓乳头呈现出典型的轮廓形态。在这两种动物中，它们的乳头体均显示出圆锥形或菌状样以及针状假乳头。在乳头沟中可见味孔。在高倍放大下可见微褶或凹坑。在猪和野猪中观察到了类似的叶状乳头。猪的叶状乳头数量较少但更宽。在乳头壁上可见味孔。在高倍放大下可见微褶。从形态学上讲，菌状乳头与其名称相符。味孔开口于上表面，通过扫描电子显微镜很容易识别。吻部和外侧区域含有大量的菌状乳头。野猪和家猪的外侧乳头每个乳头都有大量的孔。这些区域在味觉敏感性方面必定被认为是重要的。两种动物的外侧乳头都可为研究提供味蕾来源。由于食物环境压力导致的角质化，两种动物的菌状乳头上皮均呈现出有凹坑的外观。丝状乳头可以是简单的也可以是复合的（有主体和毛）。大的圆锥形乳头位于尾部并朝同一方向弯曲。丝状乳头和圆锥形乳头在食物咀嚼、处理和吞咽中起作用。
