[New findings on the innervation of nerves proper]

The study by the author and his co-workers of the innervation of the sheaths of extraorganic (spinal and cerebral) and intraorganic nerves has shown that their nervous apparatus is differentiated in accordance with differentiation of epi-, peri- and endoneurium. The peculiar features of the innervation of sheaths of different nerves correspond to their functions and pathoplastical individuality and manifest themselves by uneven complexity, concentration and microtopography of nerve structures in the sheaths and by distinctions in the development and reactivity. Interrelationships and correlation was established between the specific functional readiness of nerve conductors and the structural organization of their sheaths' nervous apparatus. The phenomenon of reciprocal innervation of nerves was established in experiment as well as earlier reactive and compensatory-reparative processes in the nervous apparatus of nerve sheaths as compared with their conductors.
