Only cranial nerves I and II are purely sensory and are responsible for the sense of smell and vision (optic nerve II). (byjus.com)
This nerve helps to feel the sense of smell. (byjus.com)
This is the primary nerve that is responsible for the smell. (byjus.com)
Damage to this nerve may result in distortion of smell and taste. (byjus.com)
Your cranial nerves help you taste, smell, hear and feel sensations. (spagades.com)

A recent review of spontaneous dissection of the internal carotid artery producing cranial nerve palsies at our institution identified nine patients. (elsevierpure.com)

Most of the cranial nerves belong to the somatic system. (byjus.com)

Groups 1 (16 symptomatic sides), 2 (14 asymptomatic sides), and 3 (16 control sides) were compared with regard to the anatomic relation between the vascular loop and the internal auditory canal and the presence of neurovascular compression of the cochlear nerve with/without angulation/indentation. (ajnr.org)
6 ⇓ - 8 Typewriter tinnitus is considered the result of dysmyelination and demyelination of the contact point between the arterial loop and the cochlear nerve that transmits an abnormal signal to the auditory cortex. (ajnr.org)
This movement triggers electrical signals along the nerve from your ear to your brain (auditory nerve). (sparrow.org)
It is the description of a noise inside a person's head in the absence of auditory stimulation. (banishtinnitus.net)

The ganglion is an enlargement of the nerve root. (lumenlearning.com)
Another type of sensory ganglion is a cranial nerve ganglion . (lumenlearning.com)
This is analogous to the dorsal root ganglion, except that it is associated with a cranial nerve instead of a spinal nerve . (lumenlearning.com)

Schwannomas can arise from all cranial nerves except the optic. (medscape.com)

They can also occur in spinal nerve roots, flexor surfaces of the upper and lower extremities, and the tongue. (medscape.com)
It typically manifests as a neuropathy involving the peripheral nerves, nerve roots, plexuses, or cranial nerves. (researchgate.net)

The stapedius muscle is the tiny muscle in the middle ear that attaches to the posterior aspect of the neck of the stapes , which when contracted dampens vibrations passed to the cochlea via the oval window . (radiopaedia.org)
The anterior and posterior gastric nerves are then formed from the esophageal plexus. (medscape.com)

There are several types of Guillain-Barré syndrome, classified by the part of the peripheral nerve involved in the condition. (medlineplus.gov)
Our special programs focus on treating brain tumors, as well as tumors in the head and neck, epilepsy, movement disorders, cranial nerve dysfunction syndromes, peripheral nerve injuries, pain, and more. (providence.org)

All cranial nerves are paired, which means they occur on both the right and left sides of the body. (wikipedia.org)
Only about 5 % of all schwannomas in the head and neck area occur on the XII cranial nerve. (thieme-connect.de)
TBI can occur as the result of a sudden, violent blow or jolt to the head. (munley.com)
