Abstract
Fascia and fascial spaces of the neck remains a controversial morphological question, which requires in-depth study, especially in the focus of prenatal morphogenesis. We have examined specimens of human embryos, prefetuses and fetuses in order to study the development and topographic-anatomical features of the neck fascial structures at different stages of human prenatal development. For this purpose, a set of microscopic methods (three-dimensional reconstruction, series of histological sections examination) for embryos (8.0-13.0 mm PCL (parieto-coccygeal length) and prefetuses (14.0-80.0 mm PCL) was used; macroscopic examination for fetuses’ specimens (80.0-230.0 mm PCL). It was found that at the end of the embryonic period of development, there are rudiments of the larynx and pharynx, which are not delimited; precrusors of vascular and nerve trunks of the neck are already present. In the prefetal we may observe change from the bilaminar to multilaminar fascial morphology. The definitive structure of fascial structures may be found in fetal stage of human ontogenesis. It is important that at fetal stage, fascial leaves tend to fuse in areas that contact with the periosteum or in the fascial spaces that do not yet contain adipose tissue yet.
