The purpose of this study was to undertake a three-dimensional comparative observation of the microvascular cast specimen (MVCS) of the filiform papillae (FiP) and fungiform papillae (FuP) on the dorsal surface of the cat tongue. By means of the corrosive resin casting technique, the MVCS of the FiP and FuP of the cat tongue were prepared and examined in detail under the scanning electron microscope (SEM). The numerous FiP and FuP distributed sporadically among the different types of the FiP were found on the entire dorsal surface of each cat tongue. A single FiP consisted of a main process (MP) which contained a large spoon-shaped concave network process and the accessory process (AP) contained a bundle of spine-like processes, arranged in a circle at the basal margin of the MP. The FiP can be classified into five types (Type I-V) according to the shape and size of the MP and numbers of the AP. Each FuP consisted of a single MP which contained an ovoid head and many AP surrounding the basal margin of the MP. The FuP can be classified into four types (FuP I-IV) according to the shape and size of the MP and numbers of the AP. The MP of the FuP, a sense organ for taste, of the cat tongue was considered to be a transformed type from the MP of the FiP, which acquires the ability to masticate and swallow functionally.
本研究的目的是对猫舌背丝状乳头（FiP）和菌状乳头（FuP）的微血管铸型标本（MVCS）进行三维对比观察。通过腐蚀树脂铸型技术，制备了猫舌FiP和FuP的MVCS，并在扫描电子显微镜（SEM）下进行了详细检查。在每只猫舌的整个背表面发现，众多FiP和FuP散在分布于不同类型的FiP之间。单个FiP由一个主突（MP）组成，该主突包含一个大的勺形凹网状突，副突（AP）包含一束棘状突，在MP的基部边缘呈环状排列。根据MP的形状和大小以及AP的数量，FiP可分为五种类型（I-V型）。每个FuP由一个单一的MP组成，该MP包含一个卵形头部和许多围绕MP基部边缘的AP。根据MP的形状和大小以及AP的数量，FuP可分为四种类型（FuP I-IV型）。猫舌的FuP的MP作为味觉感受器，被认为是从FiP的MP转变而来的类型，在功能上获得了咀嚼和吞咽的能力。
