The purpose of this study was to undertake a three-dimensional comparative observation of the angioarchitectural form, functional distributive pattern, and to classify the fungiform papillae (FuP) found sporadically and geometrically on the oblique lines of the filiform papillae (FiP) on the entire dorsal surface of the crossbred Japanese cat foretongue in microvascular cast specimens (MVCS). By means of the corrosive resin casting technique, the MVCS of the FuP of the cat tongue were prepared and examined in detail under the scanning electron microscope (SEM). With regard to the arrangement of FiPs and FuPs on the frontal half of the antero-dorsal surface of the cat foretongue, FiP types I-V and FuP types I-IV are arranged a A form with the point in the direction of the apex and in an oblique line running from the antero-central portion to both postero-peripheral portions. In the rear half of the antero-dorsal surface of the foretongue, FiP types I-V and types FuP I-IV are arranged in a V form with the point in the direction of the radix and in an oblique line running from both antero-peripheral portions to the postero-median portion or towards the pharynx on the anterior centro-dorsal surface of the cat foretongue. With the FuP arranged in the medial zone (M) and peripheral zone (P) running from the central to the apical parts, both the peripheral parts and the pharyngeal can be classified into four types (FuP types I-IV) according to the shape and size of the main process (MP), the number of the accessory processes (AP) and the regional position of the lozenge arrangement. FuP Types I-III consisted of a MP containing a large half oval, network-like process, and the AP contained a bundle of spine-like processes arranged radially in a circle at the anterior basal margin of the MP. The FuP Type IV was made up of only one MP. In the central zone (C) of a lozenge part arranged in the A and V forms, there was no FuP as a taste organ. It was assumed that in the lozenge arrangement of the A and V forms, except for the C zone, FuPs could be classified into four types (FuP types I-IV) from the frontal portion of the antero-dorsal surface toward the pharynx on the foretongue, and would play an assistant functional role in receiving the sense of taste of foods and liquids.
本研究旨在对杂种日本猫前舌整个背表面丝状乳头（FiP）斜线上散在且呈几何分布的菌状乳头（FuP）进行血管构筑形态、功能分布模式的三维对比观察，并对其进行分类。通过腐蚀树脂铸型技术制备猫舌FuP的微血管铸型标本（MVCS），并在扫描电子显微镜（SEM）下进行详细观察。关于猫前舌前背表面前半部分FiP和FuP的排列，FiP I - V型和FuP I - IV型呈A形排列，尖端指向舌尖方向，位于从前中央部分到后周边部分的斜线上。在前舌前背表面后半部分，FiP I - V型和FuP I - IV型呈V形排列，尖端指向舌根方向，位于从前周边部分到后正中部分或朝向猫前舌前中央背表面咽部的斜线上。FuP分布于从中央到顶端部分的内侧区（M）和周边区（P），周边部分和咽部可根据主突（MP）的形状和大小、副突（AP）的数量以及菱形排列的区域位置分为四种类型（FuP I - IV型）。FuP I - III型由一个包含大半椭圆形、网状突起的MP组成，AP包含一束在MP前基缘呈放射状圆形排列的棘状突起。FuP IV型仅由一个MP组成。在呈A形和V形排列的菱形部分的中央区（C），没有作为味觉器官的FuP。据推测，在A形和V形的菱形排列中，除C区外，从舌前背表面前部到咽部，FuP可分为四种类型（FuP I - IV型），并在接收食物和液体的味觉方面发挥辅助功能作用。
