The current study was done to provide comprehensive information on the anatomical features of the lips and cheeks of the goat by gross examination and morphometric analysis in addition to scanning electron microscope (SEM). Samples from 12 normal healthy adult goat's heads of both sexes were collected directly after slaughtering. The lips and cheeks were dissected, and specimens were collected for both light and SEM. The lips of goat were soft and mobile. The free border of both lips was characterized rostrally by the presence of labial projections. The number, size, and arrangement of labial projections differed in the upper and lower lips. On the other hand, the buccal papillae were arranged into 6-8 longitudinal rows parallel to the cheek teeth. The length of these papillae decreased caudally while they were absent on the most caudal part of the cheek. Presence of several types and shapes of labial projections and papillae, and buccal papillae suggest a high degree of mechanical adaptation of the lips and cheeks of the goat. This study provides baseline data for clinical studies. This study is the first report to shed light on the morphology of the lips and cheeks of the goat by gross and scanning electron microscopy.
本研究旨在通过大体检查、形态计量分析以及扫描电子显微镜（SEM），提供有关山羊嘴唇和脸颊解剖特征的全面信息。在屠宰后，直接采集了12个正常健康成年山羊（雌雄各半）的头部样本。对嘴唇和脸颊进行解剖，并采集样本用于光学显微镜和扫描电子显微镜观察。山羊的嘴唇柔软且可活动。双唇的游离缘在吻侧具有唇突。上下唇的唇突数量、大小和排列有所不同。另一方面，颊乳头排列成6 - 8排平行于颊齿的纵行。这些乳头的长度向尾侧逐渐减小，在脸颊最尾端部分则不存在。多种类型和形状的唇突、乳头以及颊乳头的存在表明山羊的嘴唇和脸颊具有高度的机械适应性。本研究为临床研究提供了基础数据。本研究是首次通过大体和扫描电子显微镜揭示山羊嘴唇和脸颊形态的报告。
