Parasympathetic fibers
- The superior salivatory nucleus contains parasympathetic axons within the intermediate nerve.
- These fibers reach the geniculate ganglion but do not synapse.
- Some preganglionic fibers persist within the greater petrosal nerve and synapse with neurons in the pterygopalatine ganglion.
- Postganglionic neurons from the pterygopalatine ganglion provide parasympathetic innervation to the lacrimal gland.
- Parasympathetic innervation to the lacrimal gland is facilitated by a communicating branch from the zygomatic nerve to the lacrimal nerve of cranial nerve V.
Sensory fibers
- The sensory component of the intermediate nerve carries input about sensation from the skin of the external auditory meatus.
- It also carries sensory information from the mucous membranes of the nasopharynx and nose.
- Taste input from the anterior two-thirds of the tongue, floor of the mouth, and soft palate is transmitted through the chorda tympani nerve and lingual nerve.
- The geniculate ganglion contains the cell bodies of the sensory component of the nervus intermedius.
- Nervus intermedius neuralgia is a pain syndrome associated with the nervus intermedius.
