[4] The superior salivatory nucleus contains the cell bodies of parasympathetic axons within the intermediate nerve.

These postganglionic neurons provide parasympathetic innervation to the submandibular and sublingual glands.

The sensory component of the intermediate nerve carries input about sensation from the skin of the external auditory meatus, from the mucous membranes of the nasopharynx and nose, and taste from the anterior two-thirds of the tongue, floor of the mouth, and the soft palate.

The sensory information from the mucous membranes of the nasopharynx and palate is carried along the greater petrosal nerve, while the chorda tympani nerve (and lingual nerve) carries taste input from the anterior two-thirds of the tongue, floor of mouth, and soft palate.

The geniculate ganglion contains the cell bodies of the sensory component of the nervus intermedius.
