Description

At the bottom of the meatus, the facial nerve enters the facial canal, which it traverses to its termination at the stylomastoid foramen. It is at first directed lateralward between the cochlea and vestibule toward the medial wall of the tympanic cavity; it then bends suddenly backward and arches downward behind the tympanic cavity to the stylomastoid foramen. The point where it changes its direction is named the geniculum; it presents a reddish gangliform swelling, the genicular ganglion (ganglion geniculi; geniculate ganglion; nucleus of the sensory root of the nerve).
