Answer:
They make synapses in the otic ganglion
Explanation:
The activity of the parasympathetic nervous system on the organs is restricted and specific, with little amplifying divergence. It acts in functions such as digestion or sleep, and is not usually activated in a generalized way, but individually and independently.
The fibers that come from the inferior salivary nucleus leave through the glossopharyngeal (IX cranial nerve), synapse in the otic ganglion and end up innervating the parotid salivary glands.
