ABSTRACT
This work was designed to study changes in the nervous apparatus of the blood vessels in the brain and spinal cord with a view to developing methods for the determination of the biological age in man. Pial and intramedullary vascular systems of the brain and spinal cord were examined in different periods of postnatal ontogenesis (between the age of 1 and 90 years) using histological, fluorescent-histochemical, and immunohistochemical methods as well as by ink injections into the blood vessels, scanning and transmission electron microscopy. The data obtained on the age-related rearrangement of the nervous apparatus of the arterial vessels in the brain and spinal cord have not only theoretical significance but can also be used for the solution of practical problems encountered in the practical work of forensic medical experts.
