Subepithelial blood vessels of the rat lingual papillae and their spatial relations to the connective tissue papillae and surface structures were demonstrated by light and scanning electron microscopy. In the rat, four types of papillae were distinguished on the dorsal surface of the tongue, i.e. the filiform, fungiform, foliate and circumvallate papillae. Vascular beds of various appearance were found in all four types of lingual papillae: a simple or twisted capillary loop in the filiform papilla; a basket- or petal-like network in the fungiform papilla; a ring-like network in the foliate papilla, and a conglomerated network surrounded by double heart-shaped capillary networks in the circumvallate papilla. These characteristic vascular beds corresponded to the shape of the connective tissue papillae and surface structures. The vascular bed beneath the gustatory epithelium in the fungiform, foliate and circumvallate papilla consisted of fine capillary networks next to the taste buds.
通过光学显微镜和扫描电子显微镜对大鼠舌乳头的上皮下血管及其与结缔组织乳头和表面结构的空间关系进行了研究。在大鼠中，舌背区分出四种类型的乳头，即丝状乳头、菌状乳头、叶状乳头和轮廓乳头。在所有四种类型的舌乳头中均发现了外观各异的血管床：丝状乳头中有简单或扭曲的毛细血管袢；菌状乳头中有篮状或花瓣状网络；叶状乳头中有环状网络，轮廓乳头中有由双心形毛细血管网络包围的聚集网络。这些特征性的血管床与结缔组织乳头和表面结构的形状相对应。菌状乳头、叶状乳头和轮廓乳头的味觉上皮下方的血管床由紧邻味蕾的精细毛细血管网络组成。
