The functional and morphological characteristics of the fungiform papillae (FuP) on the anterior dorsal surface of the cat and rabbit tongues were studied and compared using a scanning electron microscope (SEM), because the comparison of the functional and morphological relationship of FuP in microvascular cast specimens (MVCS) between these tongues is as yet not clear. In both species, FuP were found to be distributed sporadically among the numerous filiform papillae (FiP). In the cat, in particular, FuP were classified into four types (FuP I-IV) according to the shape and size of a main process (MP) and the number of accessory processes (AP). Each FuP, (FuP I-III lay along oblique lines of FiPs) contained a MP and many APs lying at the anterior basal margin of the MP, whereas FuP IV contained only the small fishnet-ball-shaped MP. In the rabbit, however, only the similar size and shape of the capillary loops, resembling the carnation flower, were scattered among FiPs on the anterior dorsal surface of the fore-tongue. These results suggest that in comparing the functional sense mechanism in both species, the FuP of the rabbit tend to be more simple than those of the cat in respect to taste sense.
使用扫描电子显微镜（SEM）对猫和兔舌背前部表面的菌状乳头（FuP）的功能和形态特征进行了研究和比较，因为这两种动物舌部微血管铸型标本（MVCS）中FuP的功能与形态关系的比较尚不清楚。在这两个物种中，FuP都散在于众多丝状乳头（FiP）之间。特别是在猫中，根据主要突起（MP）的形状和大小以及副突起（AP）的数量，FuP被分为四种类型（FuP I-IV）。每个FuP（FuP I-III沿着FiP的斜线排列）都包含一个MP和许多位于MP前基缘的AP，而FuP IV仅包含小鱼网状的MP。然而，在兔中，仅在前舌背表面的FiP之间散布着类似康乃馨花的大小和形状相似的毛细血管袢。这些结果表明，在比较这两个物种的功能感觉机制时，就味觉而言，兔的FuP比猫的FuP更简单。
