Greater superficial petrosal nerve
The greater (superficial) petrosal nerve originates at the geniculate ganglion, where the nervus intermedius and facial nerve join. It contains mainly preganglionic parasympathetic fibers and some sensory taste afferent from the soft palate
It arises at the geniculate ganglion ,passes through a hiatus in the petrous bone to reach middle cranial fossa, lying between the two layers of the dura mater towards foramen lacerum where it joined by the deep petrosal nerve (sympathetic fibres from the internal carotid artery) to form the nerve of the pterygoid canal (a.k.a Vidian nerve).
Its parasympathetic fibers relay in the pterygopalatine ganglion.
