Normal fetuses 14 to 17 days old were obtained from female Wistar rats. The palates have been studied, after dissection, by scanning electron microscopy. Palatal closure is achieved, in the median and posterior region, by the elevation of the lateral palatine processus from a ventro-medial to a horizontal position; immediately after the horizontalization, they adhere to each other. Rostrally naso-palatine canal closure takes place later; it results from an epithelial and mesenchymal outgrowth under the nasal septum. The mutual adhesivity of the free edges of the lateral processes is noticeable. The pattern of the fusion surface has been considered, elements such as exfoliated cells, filopodes and microvilli are present. Their contribution to the adherence phenomenon is discussed.
从雌性Wistar大鼠获取14至17日龄的正常胎儿。解剖后，通过扫描电子显微镜对腭部进行了研究。腭部在中后部区域通过外侧腭突从腹内侧位置抬高至水平位置而实现闭合；水平化后立即相互粘连。在鼻腭管的前端闭合发生较晚；它是由鼻中隔下方的上皮和间充质生长形成的。外侧突游离边缘的相互粘附性很明显。已经考虑了融合表面的模式，存在诸如脱落细胞、丝状伪足和微绒毛等元素。讨论了它们对粘附现象的作用。
