By means of the fluorescent-histochemical method for revealing monoamines in combination with morphometric analysis and radiologic testing, the thyroid gland activity has been estimated. The spatial characteristics of the perivascular and parafollicular adrenergic plexuses are closely interrelated in time with fluctuations of the specific thyroid function that accompanies the development of the organism's adaptation. Redistribution of the monoamines transport canals towards structures of the greatest functional strain results in an increased density of the parafollicular sympathetic neural apparatus which directly performs the adaptational-trophic influence on thyrocytes. This ensures the status of a moderate hyperactivity in the organ.
