E system: exercise, excitement, emergency, embarrassment: sns and vascular tone, blood vessels kept in a state of partial vasoconstriction; blood shunting possible via variations in sympathetic output to speci c vessels. 5: pns & tone: tonic slowing effect on heart, regulation of contractile activity of smooth muscle of gi & urinary tracts- can be overridden by. Sns (i) systems regulated in opposite directions by the sns and pns, (ii) cooperative effects of the sns & pns, (iii) unique regulatory roles of the.
