vidian nerve

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
