Sympathetic postganglionic fibers are longer than parasympathetic postganglionic fibers.

Question

Quizplus · Accepted Answer

Sympathetic postganglionic fibers are typically longer than parasympathetic postganglionic fibers. This is because the sympathetic nervous system is designed to activate the body's fight or flight response, which often requires a more widespread activation of body systems. In contrast, the parasympathetic nervous system is designed to promote rest, digestion, and relaxation, which typically only require more localized activation of body systems.
