This study described the morphological features of the Persian leopard (Panthera pardus saxicolor) tongue using light and scanning electron microscopy techniques. The keratinized filiform papillae were distributed all over the entire dorsal surface of the tongue and contained small processes. They were changed into a cylindrical shape in the body and conical shape in the root. The fungiform papillae were found on the apex and margin of the tongue. Few taste pores were observed on the dorsal surface of each papilla. The foliate papillae on the margins of the tongue were composed of several laminae and epithelial fissures. Taste buds were not seen within the non-keratinized epithelium. The vallate papillae were six in total and arranged in a "V" shape just rostral to the root. Each papilla was surrounded by a groove and pad. Taste buds were seen within their lateral walls. Lyssa was visible on the ventral surface of the tongue tip and was found as cartilaginous tissue surrounded by thin connective tissue fibres. The core of the tongue was composed of lingual glands, skeletal muscle and connective tissue. These glands were confined to the posterior portion of the tongue and were composed of many serous cells and a few mucous cells. The results of this study contributed to the knowledge of the morphological characteristics of the tongue of wild mammals and provided data for the comparison with other mammals.
本研究利用光学显微镜和扫描电子显微镜技术描述了波斯豹（Panthera pardus saxicolor）舌头的形态特征。角质化丝状乳头分布于整个舌背表面，且含有小突起。它们在舌体部变为圆柱形，在舌根处变为圆锥形。菌状乳头位于舌尖和舌缘。每个乳头的背表面观察到少量味孔。舌缘的叶状乳头由几个叶片和上皮裂隙组成。在非角质化上皮内未见味蕾。轮廓乳头共有六个，在舌根前方呈“V”形排列。每个乳头被一个沟和垫包围。在其侧壁内可见味蕾。在舌尖腹面可见齿状突，为被薄结缔组织纤维包围的软骨组织。舌的核心由舌腺、骨骼肌和结缔组织组成。这些腺体局限于舌的后部，由许多浆液细胞和少量黏液细胞组成。本研究结果有助于了解野生哺乳动物舌头的形态特征，并为与其他哺乳动物进行比较提供数据。
