To determine:

In what way the emergence of sympathetic fibers from the spinal cord differs from the emergence of parasympathetic fibers.

One of the differences between these fibers is that the preganglionic fibers of the sympathetic fibers are shorter while the preganglionic fibers of the parasympathetic fibers are longer.
