The facial nerve enters the petrosal bone via the '''internal acoustic meatus''' along with the vestibulocochlear nerve. The facial nerve also runs inside the '''facial canal'''. There are a number of intermediate branches which seperate from the main facial nerve inside the facial canal including the '''greater petrosal nerve''', the '''stapedial nerve''' (motor) and the '''chorda tympani'''. These then emerges via the '''stylomastoid foramen''' at the caudoventral aspect of the skull. The chorda tympani of the facial nerve represents the '''special visceral afferent fibre''' supplying taste to the rostral 2/3 of the tongue.
