Ninja Nerds!
In this lecture Professor Zach Murphy will discuss the trigeminal nerve (cranial nerve V). We go into great detail on the origin, course, and structures supplied by the trigeminal nerve. We also discuss trigeminal neuralgia and the management of this condition. We hope you enjoy this lecture and be sure to support us below!

***** CORRECTION**** at 47:48 I said the middle meningeal artery runs through the foramen ovale and that is incorrect it actually runs through the foramen spinosum and travels in between the dura mater and skull bone. I'm sorry for that mistake. Hope this video helps!!!

[@DaveBuikema]

MMA - Middle Meningeal Artery Spine - Foramen Spinosum I remember this one by thinking of an MMA fighter breaking someone's spine. Hope it helps someone!

[@a12oma64]

you didnt talk about the branch to maxillary sinus

[@a12oma64]

btw u are beyond amazing

[@drnandhu1]

The accessory meningeal artery runs through the foramen ovale. (MEAL) mandibular nerve, emissary vein, accessory meningeal artery, lesser petrosal nerve are the structures transmitted by ovale

[@SoloJedi_]

Thanks for the correction

[@Dentalogix]

This is unbelievable. I am a dentist, practicing for years now, phenomenal explanation. you are like a robot, projecting everything in 3D (perspective) Daamnn impressive. Thank you for your great work.

[@sandimasdoc]

I have been a dentist for decades now, and of course the trigeminal nerve is paramount to the practice of dentistry, However my understanding was superficial. I went back for my Master's in Pain management and began looking for videos that could explain the trigeminal in detail--there are a bunch of superficial ones out there. There are only a couple with the detail, excellent anatomic illustrations, and clear explanation needed by someone who needs advanced knowledge. This is one of them. It is great for everyone else too--but it remains one of my go to videos for neuanatomic detail. Kudos for such a great vid!

[@queenpower9514]

"Dentist for decades", "trigeminal nerve is paramount to the practice", "my understanding was superficial". How can this make any sense or that it's legal for a practicing provider to not know something in detailed after decades of practicing? I mean you call yourself "doctor" right? Or is "doctor of dentistry" means "a little better than hair dresser"?

[@stevefreeman7894]

You're knowledge of the trigeminal nerves are amazing! I'm watching this because my wife has burning mouth syndrome. Her palate, tongue, and teeth are burning continuously at extreme pain levels. Medications are no longer managing the pain. We are working with neurologists, GP, etc. all smart people that have run out of options for my wife. Because her pain is through maxillary and mandibular nerves this seems to cause confusion on where to look for treatment. What is your thought on her nerve pain?

Small correction, but at 17:56 the more medial branch of the frontal nerve is the Supratrochlear, whereas the more lateral branch is the Supraorbital. Just saying because I missed a tagged structure because I got the two mixed up. But all in all this was a phenomenal video to learn about the trigeminal nerve for my upcoming exam, and definitely beat the lecture explanation of this! Keep up the good work and thanks for making these videos!!

First Maxillary Molar is actually innervated by both Posterior Superior Alveolar Nerve ( Palatine and Disto buccal roots) and Middle Superior Alveolar Nerve ( Mesio Buccal root). Thank you for your lecture! The best! :)

[@user-xx7ed7ti1z]

Hi, I was looking through the comments to see if anyone had pointed that out. I partially agree, the first molar is innervated by 3 branches, the mesial root by MSA, the distal by PSA and the palatine by the palatine nerve. At least that's how they taught us, so for the anesthesia to take effect for the first upper molar, we have to aim for these three branches. Best lecture I have ever attended, kudos to you, Zach and your team

[@revalidandonacalifornia]

@@user-xx7ed7ti1z Actually Palatine root is also innervated by Posterior Superior Alveolar Nerve. The reason you have to anesthetize Palatine nerve is because of palatine mucosa. Only for extraction. For restoration just PSA and MSA you'll be fine. Thank you for your comment :)
