中文摘要
目的： 本研究旨在利用扫描电子显微镜（SEM）分析对金豺（Canis aureus）的舌部结构进行表征。
方法： 本研究检查了三只成年金豺（n = 3）的舌，平均体重为9.77 ± 1.68 kg。从舌的各个区域采集组织样本，使用梯度浓度的丙酮固定，并使用Sigma 300 Zeiss Gemini FE-SEM进行分析。
结果： 结果在金豺中鉴定出四种不同类型的乳头：丝状乳头、圆锥乳头、菌状乳头和轮廓乳头。丝状乳头具有三角形主体，周围有多个次级突起，为食物摄取和梳理提供机械表面。圆锥乳头在舌根部观察到两种不同形态，尖端尖锐或圆钝，有助于吞咽时食物向后移动。菌状乳头分布于整个舌表面的丝状乳头之间（舌根除外），而轮廓乳头共有四个，每个由圆形主体和环状垫组成，二者之间由沟分隔；两种类型均具有味觉感知功能。有趣的是，在其他一些食肉物种中发现的叶状乳头在本研究的所有样本中均未鉴定到。
结论： 这些SEM发现表明，虽然金豺的总体乳头形态与其他犬科物种一致，但在圆锥乳头的形状和数量上表现出特定差异，并以缺乏叶状乳头为特征。
英文摘要
OBJECTIVE: This study aimed to characterise the lingual structures of the Canis aureus using SEM analysis.
METHODS: This study Tongues of three adult Canis aureus (n = 3) with a mean body weight of 9.77 ± 1.68 kg were examined. Tissue samples collected from various regions of the tongue were fixed using sequential concentrations of acetone, they were analysed using a Sigma 300 Zeiss Gemini FE-SEM.
RESULTS: The results identified four distinct types of papillae in Canis aureus: filiform, conical, fungiform and circumvallate papillae. Filiform papillae featured a triangular main body surrounded by multiple secondary processes, providing a mechanical surface for food prehension and grooming. Conical papillae were observed in two distinct forms at the base of the tongue with pointed or rounded tips facilitating the backward movement of food during swallowing. Fungiform papillae were distributed among the filiform papillae across the lingual surface (except at the base), while circumvallate papillae numbered four in total, each consisting of a rounded main body and a ring-shaped cushion separated by a groove; both types function in gustatory perception. Interestingly, leaf-like papillae, which are found in some other carnivorous species, were not identified in all samples in this study.
CONCLUSION: These SEM findings demonstrate that while the general papillary morphology of Canis aureus aligns with other Canidae species, it exhibits specific differences in the shape and quantity of conical papillae and is characterised by the absence of foliate papillae.
