 Which structural difference between the parasympathetic and sympathetic nervous systems explains their functional divergence?

Answer

Both systems use norepinephrine as their primary neurotransmitter at the effector synapse.

Answer

Parasympathetic ganglia are located near the spinal cord, while sympathetic ganglia are near target organs.

Answer

Sympathetic fibers originate from cranial and sacral regions, while parasympathetic fibers originate from thoracic and lumbar regions.

Answer

Sympathetic fibers lack myelinated preganglionic axons, unlike parasympathetic fibers.
