Abstract

The lack of a sufficient amount of data on the structural features of the paraneural structures of the sciatic nerve at different periods of ontogenesis contributed to the conduct of this study, as a result of which it was revealed that with an increase in the number of days from the moment of birth, a complication of the structure of the «paraneuria» was observed in an inextricable connection with the complication of the structure of the endo, peri-, epineuria and the conductive component of the sciatic nerve. «Morphological improvement» was manifested both in the appearance of new structures in the «paraneuria» and in a change in the ratio of the cellular and fibrous components of the connective tissue, which is its morphological substrate.

Keywords
