Name a nerve associated with the parasympathetic division.

Explanation:
The vagus nerve is the main conduit for parasympathetic signals, providing the majority of parasympathetic outflow to the heart, lungs, and much of the digestive tract. Its fibers originate in brainstem and extend to organs, helping slow heart rate, constrict airways, and promote digestion. The optic nerve transmits visual information and is purely sensory, with no parasympathetic role. The sciatic nerve is a major somatic nerve serving the lower limb, not involved in parasympathetic control. The vomeronasal nerve is linked to pheromone detection in the nasal area, not autonomic regulation.
