Adrenergic (sympathetic) innervation of the precapillary sphincters in the microcirculatory bed of the rat mesentery was studied with Falck-Hillarp's method. It was shown that the precapillary sphincters are characterized by high density of the adrenergic innervation structures and specific architectonics. The results allow one to consider the adrenergic apparatus of the precapillary sphincters as a morphological substrate of their nervous regulation, thus indicating direct participation of sympathetic innervation in the sphincter function in the microcirculatory bed.
