This quiz tests your knowledge of the parasympathetic nervous system, specifically the pathway of preganglionic secretomotor fibers from the superior salivatory and lacrimal nucleus to the pterygopalatine ganglion. Learn about the cranial nerves, brain structures, and ganglia involved in this process. Refresh your understanding of the sympathetic and parasympathetic nervous systems.
