Neurology | Glossopharyngeal Nerve: Cranial Nerve IX

Official Ninja Nerd Website: ninjanerd.org
Ninja Nerds!
In this lecture Professor Zach Murphy will be teaching you about the Glossopharyngeal nerve (cranial nerve IX). We will be going into detail on this nerves origin, course, and the structures supplied by the glossopharyngeal nerve (cranial nerve IX). We also briefly discuss glossopharyngeal neuralgia, and the effects it can have on the body. We hope you enjoy this lecture and be sure to support us below!

Lmao this guy is way better than our medical professors.

+Mahdi Katz lol!! I'm so happy we were able to help!!!

[@sarahu.k7162]

@@NinjaNerdOfficial I am one of your biggest fans and your videos helped me alot , but there is a mistake in this video and the vagus nerve video. the glossopharyngeal nerve innervates the carotid body and sinus by (GVA) fibers so it transmits information about blood pressure to the medulla and here comes the vagus nerve role where it transmits those informations to the cardiac plexus by (GVE) fibers causing a change in heart rate according to the blood pressure state. ... or am I the one getting it wrong ? I will be glad if you answer my question.

My daughter has a lymphatic malformation at the base of her tongue and above her epiglottis-she experiences severe pain even though the lesion has been shrunk significantly with sclerotherapy injections. This week we are attempting a glossalpharangeal nerve block to attempt to alleviate her severe pain. Thank you for the lesson so I can better understand her diagnosis and treatments!

How is your daughter doing now? I hope she doesn’t have pain anymore

I enjoyed watching your video. I have glossopharyngeal neuralgia. Back in 2003 I had brain sure to help relieve the pain. I have other symptoms and was not sure why. But since I watch your video I now understand that they come from the G nerve. We call them my G attacks.

[@Cmysteryman]

wouldnt the fibres from the carotid body and sinus be considering special visceral afferent (though i know its not like a specific sense - then would make sense why they would go to tractus solitarius) also, in my instant anatomy booklet it says the GVA fibres from the pharyngeal mucosa, tonsils and tongue go to the sensory nucleus of V ???? which one is correct?? (there is no mention of that vagus nucleus in my book)

[@TheSM4ever]

Hey there. About your question on why aren´t the fibers from the carotid body and sinus considered special visceral afferent I think i can explain that to you. Those types of fibers include things like the sense of taste and the sense of smell. From what i read in my text books those are the only examples Hope I helped :)

lesser petrosal isnt only presynaptic fibers? i think that auriculotemporal gives the postsynaptic fibers?

[@cebrsheridan1941]

HERO 👏🔥🤓

[@TheNenannena]

N glossopharyngeus is picking up gustative sensations from papillae vallatae and foliatae not fungiformes if I'm not wrong. For fungiformes it should be n intermedius (VII)

[@NinjaNerdOfficial]

+Dragana Trifunovic have you seen our video on gustation. Check it out!!!🤓

[@WilliamGoo98]

I think so

[@samarmohammed7942]

Definitely I agree with you. fungiform papillae through intermediate nerve and CN VII

[@michsportsfan2000]

Great video. How can I ask a question to instructor?

[@cathydaae3374]

And they say there's no Creator. That is awesome!

[@snakez8407]

From 22:30 he says touch, pain & temperature fibers of GVA, but isn't touch, pain & temperature sensations usuallly GSA ( general somatoafferent) fibers? And GVA fibers are responsible for the taste sensation from the tongue?

[@anitakocab8865]

True, he also made a mistake with the papillae fungiformes, they are found in front of the sulcus terminalis and are connected with the facial nerve not the glossopharygeal

[@medlocks6732]

No taste is SVA

[@medlocks6732]

Taste is special sense.

[@mactoop]

I dont quite get it. Does the nerve from Inferior salivatory nucleus exit foramen jugulare and formanen ovale?

[@NinjaNerdOfficial]

+Alexander Top Marchant Great question! The glossopharyngeal nerve does exit the posterior cranial fossa through the jugular foramen. However there are certain fibers that make up the glossopharyngeal nerve. One of these fibers are called GVE fibers which are parasympathetic fibers. Once the GBE fibers move out of the posterior cranial fossa via the jugular foramen. The GVE fibers next enter into the middle ear cavity through the tympanic canaliculus then from there it moves up onto the promontory of the middle ear where interacts with some of the sympathetic fibers that branch off of the carotid plexus. From that point on these parasympathetic fibers(GVE fibers) move up into the middle cranial fossa through the hiatus of the lesser petrosal nerve then the lesser petrosal nerve(which are still GVE fibers of the glossopharyngeal nerve) moves out of the middle cranial fossa through the foramen ovale. it will progress until it reaches what's called the otic ganglion. From there postganglionic parasympathetic fibers(GVE fibers) progress until they reach the parotid gland. Where they will stimulate salivary gland secretion. Does that clarify your question?

[@mactoop]

Yes! Thank you very much! These videos are SO helpful for my neuroanatomy exam! Great work!
