[The morphological patterns in the variability of the adventitial nerve plexuses of the arteries of the internal organs in the stages of human postnatal ontogeny].

Productive phase and periods of stabilization and involution of organ innervation development were identified according to criteria of significant alteration of quantity of nerves forming plexuses in arterial wall, myelinated fibres (MF) total and group content that were studied micromorphometrically on serial cross sections of 12 neurovascular complexes of human organs belonging to different age groups. Signs of organ specificity, asynchronous organ innervation development and phenotypic differences of organ innervation connections are given. It is proposed that magistral artery and its network in the organ serve as a morphogenic field for its neural connections development.
