The development of nasal cavity was traced in human embryos. The identity in the primitive formation of the mouth cavity and that of the nasal cavity is stated. During embryogenesis, the primitive nasal cavities are demonstrated to change their position concerning the mouth cavity. Epithelial "cluster" formation in the area of the nostrils is examined: it appears in embryos of 16-19 mm long, is mostly prominent in embryos of 50-55 mm long, is absent in fetuses of 5.5 months old. By comparing the terms and dynamics in the development of epithelial adhesion in the larynx an the nostrils, the importance of these temporal structures for protecting the respiratory tract of the embryo from amniotic fluid is demonstrated.
在人类胚胎中追踪鼻腔的发育过程。阐述了口腔和鼻腔原始形成过程中的一致性。在胚胎发生过程中，原始鼻腔相对于口腔的位置发生了变化。对鼻孔区域上皮“簇”的形成进行了研究：它出现在长度为16 - 19毫米的胚胎中，在长度为50 - 55毫米的胚胎中最为明显，在5.5个月大的胎儿中不存在。通过比较喉和鼻孔上皮粘连发育的时间和动态变化，证明了这些临时结构对于保护胚胎呼吸道免受羊水影响的重要性。
