 SNS stimulation constricts most systemic blood vessels, especially those of the abdominal viscera and the skin of the limbs.

 PNS stimulation has almost no effect on most blood vessels.

 Presynaptic α2 vascular receptors mediate vasodilation, whereas postsynaptic α1 and α2 vascular receptors mediate vasoconstriction.

 Postsynaptic α2‐vascular receptors predominate in the venous circulation.

 Postsynaptic α2‐receptor activation causes arterial and venous vasoconstriction.

 Postsynaptic β receptors are predominantly β2 and mediate vasodilation.
