The geniculate ganglion (from Latin genu, for "knee" [1]) is a bilaterally paired special sense ganglion [2] of the intermediate nerve component of the facial nerve (CN VII). [3] It is situated within facial canal of the head .
In neuroanatomy, the cranial nerve ganglia are ganglia of certain cranial nerves. They can be parasympathetic or sensory. [ 1 ] All cranial nerve ganglia are bilateral.
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.
The epibranchial or epipharyngeal placodes generate the distal portion of the ganglia of cranial nerves VII, IX and X: [3] The geniculate placode, associated with the first pharyngeal groove, generates the geniculate ganglion and distal parts of cranial nerve VII; The petrosal placode, associated with the second pharyngeal groove, generates the ...
The cranial nerves give rise to a number of ganglia, collections of the cell bodies of neurons in the nerves that are outside of the brain. These ganglia are both parasympathetic and sensory ganglia. [10] The sensory ganglia of the cranial nerves, directly correspond to the dorsal root ganglia of spinal nerves and are known as cranial nerve ...
Geniculate ganglionitis or geniculate neuralgia (GN), also called nervus intermedius neuralgia, Ramsay Hunt syndrome, or Hunt's neuralgia, is a rare disorder characterized by severe paroxysmal neuralgic pain deep in the ear, [1] that may spread to the ear canal, outer ear, mastoid or eye regions.

A ganglion (pl.: ganglia) is a group of neuron cell bodies in the peripheral nervous system. In the somatic nervous system , this includes dorsal root ganglia and trigeminal ganglia among a few others.
