6 © 2013 Pearson Education, Inc. How is it possible that norepinephrine can cause vasoconstriction in one location but vasodilation in another? a) Sometimes norepinephrine is released by the parasympathetic nervous system, which causes relaxation. b) Receptor types differ in these tissues. c) Norepinephrine is not released by the parasympathetic nervous system. d) It can't: Its actions are predictable no matter the tissue.

14 © 2013 Pearson Education, Inc. In general, sympathetic innervation of visceral organs via the lumbar and sacral splanchnic nerves inhibits the activity of these organs. This is logical because _____. a) sympathetic input primes the body to enter a resting state b) sympathetic input is always inhibitory c) parasympathetic innervation is lacking from this area d) sympathetic activity primes the body for physical activity and temporarily shuts down noncritical body activities
