Relation of efferent impulse activity in splenic nerve to reflexly induced reactions of resistance and capacitance vessels to spleen.
Constrictory responses of splenic resistance vessels arising under pressor reflexes were abolished by hexonium (2 mg/kg) as well as the high amplitude (above 15 muV) impulses in sympathetic splenic nerves. Constrictory and dilatory responses of splenic capacitance vessels were preserved after administration of the same dose of hexonium and correlated as to the directivity with the changes of the low amplitude (15 muV and lower) impulsation in the splenic nerve.
