NCIt definition : A collection of cell bodies of cranial nerve VII found in the brainstem. There are
three nuclei with distinct functions: the facial motor nucleus, which sends muscular
efferent nerves to the muscles of facial expression and the stapedius; the superior
salivary nucleus, which sends visceral parasympathetic efferent nerves mostly to the
lacrimal and salivary glands; and the geniculate ganglion, which receives mostly afferent
nerves for taste sensation.;
