A morphological investigation of 32 histological sections of human embryos by means of their fixation in 10-12% solution of neutral formalin has been performed. The preparations have been dehydrated by carrying them through a battery of alcohols with the subsequent pouring into paraffin. The serial histological sections have been made by a sliding microtome, then coloured by keeping them in hematoxylin and eosin or boric carmine within 1-3 days, and studied by a microscope or a binocular magnifying glass MBS-10. To study the peculiarities of the form, position and relief of the structures of the nasal area the classical methods of the graphic and plastic reconstruction have been used. The morphometry has been made by a micro ruler. It has been established that at the beginning of the embryonic period nasal placodes are anlaged, while in the middle of the embryonic period the nasal fossae are formed on their free surface. The nasal fossae are restricted by horseshoe-shaped eminences that are thickened in the form of toruli – the initial stage of the formation of the middle and lateral nasal processes. Later on an intensive growth of the nasal fossae and the adjacent structures occurs and as a result they are transformed into nasal cameras. At the end of the embryonic period a break of the nasal cameras into the primary oral cavity with the formation of the primary choanae takes place. The nasal septum is formed via a fusion of the middle nasal processes. The primary nasal cavity is separated from the primary oral cavity by the primary palate.
