Why are the effects of the sympathetic division more widespread than those of the parasympathetic division of the ANS?
Fill in the blank(s) with the appropriate word(s).
The sympathetic distribution covers a larger area than that of the parasympathetic division. Also, the sympathetic
division shows extensive divergence, with each preganglionic fiber innervating as many as 32 second-order
neurons in different ganglia, whereas the maximum number of contacts for a parasympathetic fiber is six.
