What is the other name of glossopharyngeal nerve?

Anatomical terms of neuroanatomy The glossopharyngeal nerve (/ˌɡlɒsoʊfəˈrɪn(d)ʒiəl, -ˌfærənˈdʒiːəl/), known as the ninth cranial nerve (CN IX), is a mixed nerve that carries afferent sensory and efferent motor information.

Which large gland is innervated by the glossopharyngeal nerve?

Containing both sensory and motor components, the glossopharyngeal nerve provides somatic motor innervation to the stylopharyngeus muscle, visceral motor innervation to the parotid gland, and carries afferent sensory fibers from the posterior third of the tongue, pharynx, and tympanic cavity.

What cranial nerve Innervates the velum?

They are all innervated by the pharyngeal branch of the vagus nerve (CN X) – apart from Tensor veli palatini – which is innervated by the medial pterygoid nerve (a branch of CN V3).

What cranial nerve is Glossopharyngeal?

The glossopharyngeal nerve is the 9th cranial nerve (CN IX). It is one of the four cranial nerves that has sensory, motor, and parasympathetic functions. It originates from the medulla oblongata and terminates in the pharynx.

What happens if the glossopharyngeal nerve is damaged?

Glossopharyngeal nerve lesions produce difficulty swallowing; impairment of taste over the posterior one-third of the tongue and palate; impaired sensation over the posterior one-third of the tongue, palate, and pharynx; an absent gag reflex; and dysfunction of the parotid gland.

What causes deviated uvula?

It is commonly seen in children. It usually presents with acute onset nasal regurgitation of fluids, rhinolalia, and palatal asymmetry. Many causes of this disease, such as infections, trauma, tumor, and brainstem lesions, etc., have been reported.

What separates the mouth from the nose?

The palate forms the roof of the mouth and separates the oral cavity from the nasal cavity.

Is glossopharyngeal neuralgia serious?

Glossopharyngeal neuralgia is a rare condition in which there are repeated episodes of severe pain in the tongue, throat, ear, and tonsils. This can last from a few seconds to a few minutes.

What causes damage to the Glossopharyngeal nerve?

Most often the damage is from a blood vessel compressing the nerve. Other causes include aging, multiple sclerosis, and nearby tumors.

What causes damage to the glossopharyngeal nerve?

How do you test for glossopharyngeal nerve damage?

After glossopharyngeal neuralgia is diagnosed, doctors may try to determine the underlying cause of the pain. Tests such as a blood test, CT scan , MRI , or X-rays may be ordered. If it is suspected that there may be problems with the blood vessels, an MR-angiogram (MRA) may also be ordered.

Where does the glossopharyngeal nerve begin and end?

Introduction The glossopharyngeal nerve is the 9th cranial nerve (CN IX). It is one of the four cranial nerves that has sensory, motor, and parasympathetic functions. It originates from the medulla oblongata and terminates in the pharynx.

What kind of pain does glossopharyngeal neuralgia cause?

Glossopharyngeal neuralgia is a disorder that is associated with repeated episodes of severe pain in the tongue, throat, ear, and tonsils.These areas are all connected to the ninth cranial nerve, also called the glossopharyngeal nerve.Episodes of pain may last from a few seconds to a few minutes and usually occur on one side of the face.

How does damage to the glossopharyngeal nerve affect saliva production?

Damage to the glossopharyngeal nerve without associated vagal nerve damage may present as mild unilateral decrease in saliva production. One study showed that the incidence of cranial nerve injuries is higher in repeat carotid endarterectomies.

Are there any over the counter medications for glossopharyngeal neuralgia?

Treatment for glossopharyngeal neuralgia is aimed at controlling the pain associated with the disorder. Over-the-counter pain medications are generally not very effective at controlling the pain. However, anti-seizure medications and anti-depressants may help relieve pain for some individuals.
