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 .
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.
In neuroanatomy, the cranial nerve ganglia are ganglia of certain cranial nerves. They can be parasympathetic or sensory. [1] ... geniculate ganglion (CN VII)
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 inferior ganglion of glossopharyngeal nerve and distal parts of cranial nerve IX; The nodosal placode, associated with 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 ...
In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus connects with the optic nerve. There are two LGNs, one on the ...
The greater petrosal nerve also conveys some special sensory nerve fibres which carry gustatory (taste) sensory information from the palate [1]: 22 that are relayed to the pterygopalatine ganglion by the lesser palatine nerves and are in turn conveyed to the geniculate ganglion by the greater petrosal nerve to synapse in the ganglion.
The genu is the bend, or flexure in the V of the internal capsule. It is formed by fibers from the corticobulbar tract.The fibers in this region are named the geniculate fibers that carry upper motor neurons from the motor cortex to cranial nerve nuclei that mainly govern muscle motion of the head and face.
