Anatomical terms of neuroanatomy |
The deep petrosal nerve is a post-ganglionic branch of the (sympathetic) internal carotid (nervous) plexus (which is in turn derived from the superior cervical ganglion, a part of the cervical sympathetic trunk) that enters the cranial cavity through the carotid canal, then passes perpendicular to the carotid canal in[1] the cartilaginous substance which fills the[citation needed] foramen lacerum to unite with the (parasympathetic) greater petrosal nerve to form the nerve of pterygoid canal (Vidian nerve).[1]
