Three-dimensional structures of the microvascular network of the filiform papillae (FiP) and fungiform papillae (FuP) on the cat tongue were observed by the corrosion cast method under a scanning electron microscope (SEM). FiP can be classified into five types, types I-V and FuP into four types, types I-IV according to the shape and size of the main process (MP) and the number of the accessory processes (AP) which are found on the anterior central dorsal surface. FuP (I-IV) were found to be distributed sporadically among FiP (I-V). Each of the types I-V of FiP were arranged the form of a in an oblique line running from the anterior central zone to the posterior peripheral zone in an orderly and geometrical fashion. Each of the types I-IV of FuP were scattered throughout in line of FiPs arranged in the form of a , the point of which is directed at right angles towards the apex. FiP play an important role in the drinking of milk and water, holding, masticating and swallowing the food and, after mixing the food with saliva, in the transporting of the food mass towards the pharynx. The MP of FuP was considered to be a modified form of the MP of FiP of the cat tongue and to function as part of a sense organ for taste.
采用铸型腐蚀法，在扫描电子显微镜（SEM）下观察了猫舌丝状乳头（FiP）和菌状乳头（FuP）微血管网络的三维结构。根据位于前中央背侧表面的主突（MP）的形状和大小以及副突（AP）的数量，FiP可分为I-V型5种类型，FuP可分为I-IV型4种类型。发现FuP（I-IV型）散在于FiP（I-V型）之间。FiP的I-V型均以前中央区向后外周区的斜线形式有序且呈几何状排列。FuP的I-IV型均散布于呈斜线排列的FiP之间，其斜线的点与舌尖成直角。FiP在猫舔食牛奶和水、抓取、咀嚼和吞咽食物以及将食物与唾液混合后将食团向咽部运输过程中发挥重要作用。FuP的MP被认为是猫舌FiP的MP的一种改良形式，起着味觉感觉器官一部分的作用。
