Будова та кровопостачання L2-S2 дорзальних корінців спинного мозку щурів різного віку

The paper presents information of hystometryc and electron microscopic research of nerve fibres of spinal cord dorsal roots and their blood circulation system of rats in the postnatal period of ontogenesis. The basic types of nerve fibres are revealed and characterized. Their composition which reflects the close morphological mutually causal structure of nerves and ways of blood microcirculatory is shown. It can determine the character of age-specific processes in the dorsal roots.
