The aim of this study was to investigate the morphology of the goat hard palate by light and scanning electron microscopy (SEM), in addition to gross and morphometric analysis. A total of twelve goat heads, from normal adult and apparently healthy goats of both sexes, were collected from local slaughterhouses in Qena province, Egypt. Samples were subjected to gross examination, morphometric analysis, light microscopy and SEM. The hard palate in the goats was long and could be divided into a rostral narrow part and a caudal wide part with about 12-15 transverse palatine ridges from which the rostral palatine ridges were serrated on their free caudal edges. The dental pad replaced the upper incisors; its caudal border had a serrated appearance. At higher magnification, the epithelial surface of the palatine rugae and incisive papilla revealed a variety in the shape of the microplicae and the pattern of the micropits. These adaptations of the goat's hard palate might increase its efficiency during ingestion and mastication of coarse roughages and in directing the food backwards. To our knowledge, this is the first study showed the detailed anatomical description of the hard palate of the goat with SEM.
本研究的目的是通过光学显微镜和扫描电子显微镜（SEM）研究山羊硬腭的形态，此外还进行大体和形态计量分析。从埃及基纳省当地的屠宰场收集了总共12个山羊头，这些山羊均为正常成年、明显健康的雌雄山羊。对样本进行大体检查、形态计量分析、光学显微镜检查和扫描电子显微镜检查。山羊的硬腭较长，可分为前部狭窄部分和后部宽阔部分，有大约12 - 15条横向腭嵴，其中前部腭嵴的游离尾缘呈锯齿状。齿垫取代了上门齿；其尾缘呈锯齿状外观。在更高放大倍数下，腭皱襞和切牙乳头的上皮表面显示出微褶形状和微凹模式的多样性。山羊硬腭的这些适应性变化可能会提高其在摄取和咀嚼粗硬草料以及将食物向后引导过程中的效率。据我们所知，这是第一项用扫描电子显微镜展示山羊硬腭详细解剖描述的研究。
