Morphogenesis of Fascial and Cellular Spaces of the Gluteal Region in Human Fetuses

Macroscopic examination of topographic and anatomical features of fascial-cellular structures in the gluteal region was carried out on 82 specimens of human fetuses aged 6-10 months. We described the splitting of the gluteal fascia into three layers: superficial, middle and deep ones. Superficial and middle layers form a fascial sheath for the gluteus maximus large muscle, which is separated from the gluteus medius muscle and the musculus tensor fasciae latae of thigh by a deep layer of the gluteal fascia. In the thick of the middle and deep layers of the gluteal fascia there are components of the formation of the upper and lower gluteal neurovascular bundles. In the fetal period of human ontogenesis in the formation of the embryo topography of the pelvic and gluteal fascial layers syntopic correlations of pelvic muscles are of certain importance. In the late gestational period of ontogenesis such parts of the parietal fascia as the obturator fascia and the piriform muscle fascia are the most developed and the gluteal fascia becomes harder.
