Based on scanning electron microscopic dissections of human embryos and fetuses of the sixth to the twelfth week (Carnegie stages 16-23 and early fetus), the origin of the nasal septum was studied. The findings show that the nasal septum does not grow downwards. It is derived from the tissue between the primary choanae: as such, its anlage is present from the very beginning. Its contact and fusion with the palatal shelves is made possible by the elevation of the palatal shelves from the vertical into the horizontal position, as the tongue descends.
基于对第六周到第十二周（卡内基分期 16-23 期和早期胎儿）人类胚胎和胎儿的扫描电子显微镜解剖研究，对鼻中隔的起源进行了研究。研究结果表明，鼻中隔并非向下生长。它源自初级后鼻道之间的组织：因此，它的原基从一开始就存在。随着舌头的下降，由于上颚从垂直位置上升到水平位置，上颚与腭骨的接触和融合成为可能。
