[The role of the ventral structures of the medulla oblongata in regulating the resistive functions of organ arterial vessels].
In the rostral part of medullary ventral areas (MVA) both the pace-maker neurons forming the tonic sympathetic activity, and the relay structures integrating the baroreceptor information on its way towards vascular areas, are located. The structures of the caudal portion of this cerebral area exert a depressing effect upon the activity of neuronal pools of the brain rostral part and modulate own baroreflexes. An obvious relationship was revealed between the character the extension of changes in the resistive function of the intestine and skeletal muscles' vessels, on the one hand, and the functional state of the MVA structures (excitation or inhibition), on the other hand.
