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.
What is vagus and glossopharyngeal nerves?
The glossopharyngeal and vagus cranial nerves provide the brainstem with sensory inputs from different receptors in the heart, lung, and vasculature. This afferent information is critical for the short-term regulation of arterial blood pressure and the buffering of emotional and physical stressors.
Is the glossopharyngeal nerve sympathetic or parasympathetic?
The glossopharyngeal nerve, or CN IX, carries motor and sensory fibers to and from the rostral pharynx, palate, larynx, and tongue. The glossopharyngeal nerve also contains a parasympathetic component that innervates the parotid and zygomatic salivary glands.
What happens if glossopharyngeal nerve is damaged?
When the glossopharyngeal nerve becomes irritated, an attack of intense electric shock-like pain is felt in the back of the throat, tongue, tonsil or ear. You may initially experience short, mild attacks, with periods of remission. But neuralgia can progress, causing longer, frequent attacks of searing pain. Figure 1.
What number is the glossopharyngeal nerve?
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 is the major function of the glossopharyngeal nerve?
The glossopharyngeal nerve carries sensory, efferent motor, and parasympathetic fibers. Its branches consist of tympanic, tonsillar, stylopharyngeal, carotid sinus nerve, branches to the tongue, lingual branches, and a communicating branch to cranial nerve X (vagus nerve).
Is marsilea Crenata edible?
As food. Sporocarps of some Australian species such as Marsilea drummondii are edible and have been eaten by Aborigines and early white settlers, who knew it under the name ngardu or nardoo. The leaves of Marsilea crenata are part of the East Javanese cuisine of Indonesia, especially in the city of Surabaya.
Is Marsilea a Biofertilizer?
– Marsilea ,a genus of approximately 65 species of aquatic fern of the family marsileaceae and it is not used as a biofertilizer.
How do you fix glossopharyngeal nerve damage?
The most effective drugs are antiseizure medicines such as carbamazepine. Antidepressants may help certain people. In severe cases, when pain is difficult to treat, surgery to take pressure off the glossopharyngeal nerve may be needed. This is called microvascular decompression.
Is the glossopharyngeal nerve sensory or motor?
The glossopharyngeal nerve as noted above is a mixed nerve consisting of both sensory and motor nerve fibers. The sensory fibers’ origin include the pharynx, middle ear, posterior one-third of the tongue (including taste buds); and the carotid body and sinus.
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.
Where does the glossopharygeal nerve travel to in the middle ear?
The glossopharyngeal nerve provides parasympathetic innervation to the parotid gland. These fibres originate in the inferior salivatory nucleus of CN IX. These fibres travel with the tympanic nerve to the middle ear.
How is decompression done for glossopharyngeal neuralgia?
The decompression addresses the root cause of glossopharyngeal neuralgia by dealing with vessel that is irritating the nerve.This minimally invasive, endoscope assisted surgery involves a keyhole retromastoid craniotomy made through a small incision behind the ear.
