Anatomical terms of neuroanatomy |
The intermediate nerve, nervus intermedius, nerve of Wrisberg or Glossopalatine nerve[1][2][3] is the part of the facial nerve (cranial nerve VII) located between the motor component of the facial nerve and the vestibulocochlear nerve (cranial nerve VIII). It contains the sensory and parasympathetic fibers of the facial nerve. Upon reaching the facial canal, it joins with the motor root of the facial nerve at the geniculate ganglion. Alex Alfieri postulates that the intermediate nerve should be considered as a separate cranial nerve and not a part of the facial nerve.[4]

The remaining preganglionic fibers continue as the mixed facial nerve proper as it extends through the facial canal. Before the nerve exits the skull via the

The geniculate ganglion contains the cell bodies of the sensory component of the nervus intermedius. Nervus intermedius neuralgia is a pain syndrome associated with the nervus intermedius.
