The lingual mucosa of the nine-banded armadillo, Dasypus novemcinctus, was studied by scanning electron microscopy in order to analyse its morphology. The tongue of the armadillo is long and thin, and has filiform, fungiform and vallate papillae. In the anterior part of the tongue and near the vallate papillae, single or bifurcated filiform papillae are found. The vallate papillae are located on the dorsal surface of the middle third of the tongue, and have two or four slender extremities. The fungiform papillae are elliptical or rounded, and are concentrated mainly on the tip and lateral surface of the tongue, reaching as far as the middle third of the dorsal surface. Their surfaces are flat and smooth on the dorsal side, with some taste pores. Their taste buds are located near the vallum. In the material for which freeze-cracking was used, the epithelial layer showed a characteristic mucosal structure, with many epithelial papillae containing blood vessels and bundles of collagen fibers. The basal epithelial surface of the tongue mucosa showed irregular projections that are rounded or polygonal in shape, with a depression in the center. These depressions varied in diameter.
为了分析九带犰狳（Dasypus novemcinctus）的舌黏膜形态，采用扫描电子显微镜对其进行了研究。犰狳的舌头又长又细，有丝状乳头、菌状乳头和轮廓乳头。在舌头前部和轮廓乳头附近，可发现单个或分叉的丝状乳头。轮廓乳头位于舌头中三分之一的背表面，有两个或四个细长的末端。菌状乳头呈椭圆形或圆形，主要集中在舌尖和舌侧面，一直延伸到背表面的中三分之一处。它们的背侧表面平坦光滑，有一些味孔。它们的味蕾位于轮状缘附近。在使用冷冻裂解处理的材料中，上皮层呈现出典型的黏膜结构，有许多含有血管和胶原纤维束的上皮乳头。舌黏膜的基底上皮表面呈现出不规则的凸起，形状为圆形或多边形，中心有凹陷。这些凹陷的直径各不相同。
