nerve of pter·y·goid ca·nal[TA]
the nerve constituting the parasympathetic and sympathetic root of the pterygopalatine ganglion; it is formed in the region of the foramen lacerum by the union of the greater and deep petrosal nerves and runs through the pterygoid canal to the pterygopalatine fossa.
A short efferent nerve formed from the merger of the deep petrosal and greater petrosal nerves. The vidian nerve carries postganglionic sympathetic axons from the superior cervical ganglion and preganglionic parasympathetic axons from the superior salivatory nucleus (in the pons); it also carries taste axons from the palate. The vidian nerve exits the skull through the pterygoid (vidian) canal and connects to the pterygopalatine ganglion inside pterygopalatine fossa.Synonym: nerve of the pterygoid canal
