The '''nerve of the pterygoid canal''' ('''Vidian nerve'''), formed by the junction of the [[great petrosal nerve]] and the [[deep petrosal nerve]] in the cartilaginous substance which fills the [[foramen lacerum]], passes forward, through the [[pterygoid canal]], with the corresponding artery ([[artery of the pterygoid canal]]), and is joined by a small ascending sphenoidal branch from the [[otic ganglion]].
Finally, it enters the [[pterygopalatine fossa]], and joins the posterior angle of the [[sphenopalatine ganglion]].
It contains preganglionic parasympathetic fibers from the [[greater petrosal nerve]], a branch of the [[facial nerve]] (CN VII), and postganglionic sympathetic fibers from the [[deep petrosal nerve]].
