The mucosa of the spotted salamander tongue and its taste organs were investigated by means of light and scanning electron microscopy. The most striking feature of the salamander tongue is an almost complete lack of papillae which are replaced by long, radially disposed folds with linear arrays of taste organs along their ridges. In respect of morphology, the taste organs of the salamander occupy an intermediate position between the taste buds of Urodela and taste discs of Salientia. Scanning electron microscopic examination of microcorrosion casts of the blood vessels of the tongue has revealed that the structure of subepidermal capillary network reflects the topography of the tongue surface and the distribution of its taste organs. In the core regions of the folds the capillary loops accompanying gustatory receptors empty via their shorter, descending arms into the draining vessels, the initial segments of which retain a course parallel to that of the folds. In the few fungiform papillae the capillary vessels form single loops whose distal ends come to lie in the vicinity of taste discs.
通过光学显微镜和扫描电子显微镜对黄斑蝾螈舌头的黏膜及其味觉器官进行了研究。蝾螈舌头最显著的特征是几乎完全没有乳头，取而代之的是长长的、呈放射状排列的褶皱，其脊上有味觉器官的线性排列。就形态而言，蝾螈的味觉器官在有尾目动物的味蕾和无尾目动物的味觉盘之间占据中间位置。对舌头血管的微腐蚀铸型进行扫描电子显微镜检查发现，表皮下毛细血管网络的结构反映了舌表面的地形及其味觉器官的分布。在褶皱的核心区域，伴随味觉感受器的毛细血管袢通过其较短的下行臂排入引流血管，引流血管的起始段与褶皱保持平行走向。在少数菌状乳头中，毛细血管形成单个袢，其远端位于味觉盘附近。
