Why the hell is this man begging for likes😭...that breaks my heart. You're truly underappreciated dude !!! You're much more worthy that those likes and follows and subscribes !
Because that's how he earns while we learn from him for free. And I think he deserves every like and subscription because of the way he teaches, draws, writes, and maintains a passion for medicine in every video he creates. Even if you hate that part of him that lasts for 3 seconds of video, don't let that part ruin the rest of the 39 minutes you can enjoy and learn quickly.
You know, even if I fail my exam, at least I´ll have rediscovered my passion for medecine. It got lost between the dry textbooks and absurd professors somewhere.
I’m not a medical student but you have really helped me to understand why the damage to my utricule causes me to have severe dizziness and balance issues. Also how the eyes, brain and inner ear work together. I have had to “retrain” these 3 to recognize the change in the “signals” they receive. I am so glad I stumbled onto your videos. Thank you for explaining it to where a non medical student could understand.
UH mazing review, as always. We are learning things a bit differently in PT school (from one of the top Vertigo therapists in the country!). I thought I'd share what I'm learning: For Anterior and Posterior Canals, we test for BPPV using Dix Hallpike (30 degrees of neck extension), but the nystagmus will torsion toward the affected canal, (right torsional will mean right canals) with the addition of beating up or down: - Ant Canal will be down-beating nystagmus - Post Canal will be up-beating nystagmus Depending on how long the nystagmus lasts, we either have a canalithiasis (60 seconds) - Canalithiasis can be treated with CRM (Canal Repositioning Maneuver or Eply's) - Cupulothiasis means the otolith is stuck on the cupula, and needs more of a Semont Maneuver (you really BONK the patient to dislodge it!), followed by CRM For Horizontal Canals, we test using the Roll Test (30 degrees of neck flexion) This will tell us which canal, based on whether the nystagmus beats towards the ground (no matter which way you turn) or away from the ground. Geotropic (towards the ground) = Canalithiasis Apogeotropic (away from the ground) = Cupulothiasis And the affected side is determined based on the side's severity of symptoms (Canal = worse symptoms, Cupula = reduced symptoms) We treat Horizontal Canalithiasis using a maneuver called the BBQ Roll! Horizontal Cupulothiasis is treated with Modified Gufoni, then BBQ... Thanks for letting me talk that out before the big final!!
Your explanations are crystal clear and detailed. There is literally no one else on the internet that has the ability to explain things so well. Thank you.
Zach I cannot express how helpful your videos are. Listening to you is truly so much more effective than reading textbooks over and over again. Love from Poland!
Dear Ninja, you are awesome explaining how fabulous our ear system is! Congratulations! Your tone and sound, of voice and expression is a gift in you and for those who listen to you. I am 76 and having a little trouble, feeling intense vertigo once in a while, but most of the time feeling like if I came out of a boat and my perception as in a low motion..
I'm studying for the IHS exam to get my Hearing Instrument Licensing certificate and these videos you did on the hears are just amazing. They have helped me understand things SO much better than the booklets I was given for studying. Thank you guys X1,000,000
greatful for this, my wife just came down with vertigo and this is helping me understand the eye movements they show in the other videos. Greatest illustration in real time also.
I am always motivated whenever I saw you getting excited and happy when you are explaining the physiology of a certain part XD I wonder how you understood Guyton and explained it to us in a very clear manner. Thank you very much!!! May more blessings shower upon you and your team !!!
Absolutely amazing. I am in awe of your astounding knowledge and how you are able to precisely explain everything almost flawlessly without missing a beat, but still in a way that I (just an average non-medical guy) can understand it all. You help me appreciate just how incredible the design, mechanism and wiring of living organisms is. Just astounding, thank you!
Love how he is enthusiastic and excited about how darn cool this is, cuz that's how "teaching" should be, especially physiology🖤💥👍 One of the most mind-blowing and awesome lectures thanks so much 🖤
Wow! This was great!! I'm trying to understand my diagnosis of "Labyrinthitis", and this helped ALOT, especially with the vertigo part!! You're great!!
I think the important fact is that the position of the kinocilia, bcz you just said the depolarization happens when the stereocilia pushes up to the kinocilia but in your picture the hair cells are on the different side
@@1TheBasketBallGang1 He says that the canals are a representation of any SCC however this is incorrect, as the Kinocilia in the drawing are facing away from the utricle therefore they have to be either the superior or posterior canal, where ampullofugal flow (away from the ampulla) is excitatory. This is opposite to the horizontal canal where the kinocilia face toward the utricle making ampullopetal flow (towards the ampulla) excitatory
Yes, You have the best explanations😮 & Yes, you're saving my exams😁 & Yes, You're THE BEST Bio teacher I've found😀😊 (who is so darn cool😎) I can't thank you enough, may you stay safe n healthy n keep teaching us the Awesome way🤟
Amazing explanation your channel is the best thank you❤️ , but in this video i was wondering shouldn’t the hair cells be in opposite sides i mean kinocilium should be to the left and the stereocilia should be in the right side in the right semicircular canal and the opposite in the left one
I have trouble understanding the planes, the canals are orientated in...could it be that you exchanged the left and right ear in your drawing at 3:19 ?
a very useful video for aerospace medicine residents or aviation medicine practitioners to understand spatial disorientation's physiology... marry me Ninja nerd!!!
The Lempert manuever is a canalith repositioning technique used to address issues with the lateral canal, not anterior. The deep head hang is used to address issues with the anterior canal, not lateral. Otherwise was a nice review. Thanks!
Ok, since you seem to have a good knowledge, here is a question for you: Why does cold water (caloric stimulation test) lead to nystagmus, even though it bends the hair cells towards the wrong direction, so no AP should be fired?
Watching your video is like watching a medical thriller movie. You can't stop at one and usually end up watching all prequels and sequels. Never know how the time flies. 👀
Thank you for wonderful lecture. But you did some mistakes at the end of lecture. AC BPPV management is deep head hanging(Yakovino maneuver), Lemperf or Gufoni maneuver for lateral canal BPPV. What a amazing physiologic lecture of vestibular system, thanks a lot ^^
As usual awesomely explained. Thanks a lot. One correction, Deep head hanging maneuver for superior/anterior SCC BPPV & Lempert maneuver for Lateral SCC BPPV.

Have you hearing loss too?
I had bad brainstem stroke ear on rightvis gone also eye you explained it to me in a way I could understand

- Post Canal will be up-beating nystagmus
Depending on how long the nystagmus lasts, we either have a canalithiasis (60 seconds)

I never commented on a video, but for real, you deserve a lot, thank you, such a great and passionate teacher
Your explanations are crystal clear and detailed. There is literally no one else on the internet that has the ability to explain things so well. Thank you.
I specially appreciate the time left at the end of each video that allows me to screenshot for taking notes on. Thank you for your consideration!
wow, i'm studying anatomy and i had so many "it makes sense now!" moments during this video. thanks for teaching us!
Zach I cannot express how helpful your videos are. Listening to you is truly so much more effective than reading textbooks over and over again. Love from Poland!
Finally understood what guyton was trying to say 😂
👍
😁👌
HAHAHAHA
You're from which country😂😂so guyton is used worldwide
Lmfaooo facts

you were born to teach! bless you
I'm a Registered Nurse. I was just looking around about Nystagmus (I used to work in the ED.) You just blew my mind! Thank you!!!!

THAT IS HOW SHOULD WE USE RUclips !!!
You have single handedly saved my neuroscience grade in med school and have restored my passion for medicine, thank you ❤

I don't know how I would survive physio without this man
Love how he is enthusiastic and excited about how darn cool this is, cuz that's how "teaching" should be, especially physiology🖤💥👍
One of the most mind-blowing and awesome lectures thanks so much 🖤
may God bless u all the time to keep teaching like this. :D i am the type who have to watch video first before open and read the textbook.
The most Handsome Mentor/Teacher for Medical students on RUclips & medschool.
Love you sir from 🇵🇰.
Hello from Belarus.this video the best one.thanks for your job.l am dr.neurologist and it was interesting for me to remember this information.
What a Way Of Teaching Sir... to Be Honest You Are A Blessing For Medical Students
Wow! This was great!! I'm trying to understand my diagnosis of "Labyrinthitis", and this helped ALOT, especially with the vertigo part!! You're great!!

Ljubomir Cirakovic , I had the same question...... did you ever get a reply ?
I think you are right! :)

Good spot, I was wondering the same thing. Thanks for highlighting
same question about the figure
Oh man, im indonesian, im a medical student, you help me a lot, big thanks bro!
Yes, You have the best explanations😮 & Yes, you're saving my exams😁 & Yes, You're THE BEST Bio teacher I've found😀😊 (who is so darn cool😎)
I can't thank you enough, may you stay safe n healthy n keep teaching us the Awesome way🤟
You've demystified my hearing science class! THANK YOU!!
Honestly one of the best youtube videos that explains the vestibular organ. Thank you so much.
Im 3 rd yr MBBS student .... I started Ent ur videos helped me a lot ... thanks for it ..love from Kashmir ♥️
So passionate and helpful... That excitement though 28:35 ... U are the best brother 👏
Thank you so much! One of the best videos about SCCs physiology on RUclips!
Amazing explanation your channel is the best thank you❤️ , but in this video i was wondering shouldn’t the hair cells be in opposite sides i mean kinocilium should be to the left and the stereocilia should be in the right side in the right semicircular canal and the opposite in the left one
im wondering the same thing
@@marianfarfan.fontalvo3539 Yes, you are correct. The kinocilium are actually on the medial side (nearest to midline) of each hair cell on both sides!
Iam like you emotion
بشر تخرجت ولا باقي ههههههههههههههه
you are the best I am spreading your videos in our batch whatssapp group, class & everywhere. Thaaaank you so much
Words are not enough to express my gratitude😭big thanks from Armenia 🇦🇲
YOUR HARD WORK IS MORE PRECIOUS THAN THESE LIKES , YOU ARE GENIUS , LOVE YOU SIR....🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰🥰
I have trouble understanding the planes, the canals are orientated in...could it be that you exchanged the left and right ear in your drawing at 3:19 ?
It is obvious you love teaching, I'm so grateful for your videos, thank you from Spain!!
You are Amazing Sir !! Your videos help me a lot and also clear all doubts which were circulating in my mind . Greatly thankfull to you Sir.
honestly your a true legend. I pray to God He blesses you
Excellent and very didactic presentation, great teaching skills. Thanks
Man, I just be letting the ads play and don't even skip so this man can get👏🏽his👏🏽money!👏🏽 😆 He is a lifesaver...
I finally understood what the heck is the semi circular canal and the nystagmus things... thanks professor.
All you"re videos are great. Look forward to seeing them ALL!
i learn so much from you than my actual lecturer. god bless
You are a genius! your video really help me! greetings from Buenos Aires´s University ( UBA) Argentina
Thank you so much Zach!! U Are Always there when I’m on the verge of pulling my hair out
thank you dr ninja, you helped me my medical journey.
thank you for the great explanations! definitely one of the best lecturer :'))
U are such a blessing to medical students
I feel like never stop listening to you! Than you so much

this is so so amazing. thank you so much for this video. gonna recommend it to my batch mates and juniors
where frm u r
i was about to waste my whole day of trying to understand this you really saved the day
It was really good , finally understood the whole thing
From Russia. Great Video. Thank you so much. Keep going
Take a bow Zach!!!!...truly incredible 🤩
Watching your video is like watching a medical thriller movie. You can't stop at one and usually end up watching all prequels and sequels. Never know how the time flies. 👀
I am a medical student and this video has helped me soooooooo much
Wow I love your excitement while explaining
you saved my life! you are hero.
Thank you, you really saved my life ❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️
Excellent teaching skills that compensate several errors.
It's just fascinating seeing your passion for delivering such information.
WORLD CLASS PRESENTATION.
Vestibular nystagmus is darn cool!! You just remained me why I choose medical. Thank you❤
I knew after watching your videos I will get everything :). Thank you so much!
Just Great explanation!
You deserve at least 100 million subscribers
you are trully a blessing!! thank you for making these videos!!
Thank you very much man.. You are born to teach
thank you for your lectures, so helpful !!!!!
What? This? For free? Whoaaaaaa 😯😯😯 thank you so much!
THANKS SO MUCH.DIMISTIFICATION ATTENDS YOUR 'MADE SIMPLE PRESENTATIONS.KEEP UP THE GREAT HELPFUL, ERUDITE WORK.
Best one for vestibular apparatus!!!!
Thank you for wonderful lecture. But you did some mistakes at the end of lecture. AC BPPV management is deep head hanging(Yakovino maneuver), Lemperf or Gufoni maneuver for lateral canal BPPV. What a amazing physiologic lecture of vestibular system, thanks a lot ^^
I hope all teachers were like this 😭
I’m speechless. Thank you so much
I can't believe I just stumbled upon your channel. I'm in the thick of A&P2 right now. Thank you for your videos!!
God bless you sir ❤️❤️🖤🖤
Amazing... Im really amazed at this video and how you explained it clearly.
You are much better than my teachers🤩I enjoy studying with your lessons.Good luck😀
You are so good its not funny. Im a medical student and this helped soo much. Continue making these kind of vids !!!
Wow
Really really you are amazing
This is the best possible way to make this hard topic easy and interesting
You did great job👏🏻👏🏻👏🏻
Thank you so much
How you are passionate about physiology 🤩 thanks ninja
I like how they're called 'maneuvers', it makes them seem as cool as doing maneuvers as a fighter pilot
BEST TEACHER EVERRR!!!
Really helpful...
I really appreciate u...
i have no words to say about you...
love you form paramedial potine reticular formation...
❤❤❤
Wonderful lecture as always, thank you so much 😊
Best teacher ever
This guy saved. My first year medical. 😭
very good explanation thank you man
thank you, eveything is so clear now!!
As usual awesomely explained. Thanks a lot.
One correction, Deep head hanging maneuver for superior/anterior SCC BPPV & Lempert maneuver for Lateral SCC BPPV.
U r life saver..
God bless u👍🏻👍🏻👍🏻👍🏻
