From which nucleus do the preganglionic parasympathetic fibers that innervate the otic ganglion originate?

Explanation

The preganglionic parasympathetic fibers destined for the otic ganglion arise from the inferior salivatory nucleus. The superior salivatory nucleus primarily supplies fibers to the pterygopalatine and submandibular ganglia, while the nucleus of the solitary tract and lacrimal nucleus serve different functions unrelated to the otic ganglion.
