[Formation of cholinergic transmission of excitation in the sympathetic nervous system].
Recording of electrical activity of the sympathetic ganglia in prematurely born mammals revealed that their cholinergic transmission of excitation developed in postnatal ontogenesis gradually along with myelinization of the fibers of preganglionic nerve and an increase in number of light synaptic vesicles in axo--dendritic terminals. With aging, the membrane potential of neurons increases, and their polyvalent chemosensitivity gets substituted with the specific cholinosensitivity. At the early stages of postnatal ontogenesis, the adrenergic and adaptationtrophic type of excitation transmission prevails in the ganglia.
