Question

Quizplus · Accepted Answer

Sympathetic responses are widespread because NE and epinephrine are secreted into the blood as part of the sympathetic response, allowing for effects on multiple organs and tissues throughout the body. Preganglionic fibers in the sympathetic nervous system are generally short and preganglionic fibers in the parasympathetic nervous system are generally long. Inactivation of ACh is fairly rapid, therefore it does not contribute to the widespread nature of sympathetic responses.
