I started getting vertigo about seven years ago, it just hit me outta the blue! Then I started getting anxiety from it. It seems like the anxiety just caused the vertigo to get worse. It became a vicious cycle. My doc gave me medicine but it didn’t always work, sometimes it made it worse. I had a CT scan of me head, which was normal. I had an MRI and nothing showed up. And I saw an ENT who didn’t believe that it was coming from my ears. Nobody could tell me what was wrong with me, and I was really starting to get very worried that it would never go away. Then I found heron program . I admit I was worried it was a scam but I was so desperate that I took the chance and I am glad I did! I felt the difference the very first day. Two days later I could walk almost normally again. And now I never have the spinning feeling in my head any more. Amazing! for more information about this program, click here HootDizzy.xyz
bruh, i've been spinning in the opposite direction for years to get rid of dizzyness, but i just thought it was psychosomatic. I never realized that there was an actual scientific explanation for it.
Great resource for student! Please do note some slight errors. First, at 2:24. The Semi-Circular canals do NOT line up with the anatomical planes, as described. They are tilted up approximately 20-30 degrees, and with the HSCC (lateral canal) following Reid's Baseline, which is a line you can draw from the edge of your tragus (notch on the outer ear that you can use to plug the canal) to the lateral canthus (edge of the eye). Second: 2:58. "Otolithis" have a hard "O" for the initial "o" (and does not sound like "auto-lith", but rather like "o-toe-lith"), in medical communities in the U.S., at least. Note these are just slight things I would want my students to know. :) Again, great resource. Thanks!

Thank you so much for this video. I really am trying to understand THAT area, since mine got destroyed by a tumor. THANK YOU for making this easy to understand!
Great info, and video. Helps me understand how my balance works now, given that my other balance systems have been understandably, and effectively destroyed, due to Neuro-Surgery for a pontine glioma (Ependymoma superior, and proximal to my brain stem), as well as an HAI (hospital acquired infection) of Serratia meningitis.
I suspect nerve ending misfires to be one of the culprits of PTSD and my GAD. I learned a lot at the Hough Ear Institute. Their meds didn't work well but, psychiatric meds have me sudden panic free.
After training, dizziness can be overcomed, astronauts can spin more than nermal people. In this case, the endolymph must still be moving, then what could be the mechanism of this resistance to dizziness?
adaptation, maybe it thickens itself or maybe its adjusted at the perception stage where it downreulates whatever stimuli, maybe we just more fast adjapting receptors instead of slow adapting or non adapting
so in bppv are the crystals from the otolithic organs? If so how are they causing dizziness in the SC canals? Are there hair cells in the SC canals? thanks
I believe BPPV results when crystals have been misplaced from the otolithic organs. That is why treatment includes particle repositioning manoeuvres, such as the Epley's manoeuvre.
I have oscillipia from a nerve being burned out due to otoxicity fro vancymycn and gentamycn. ^ yr **** is moving all around 24/7. No quality left in life. Can't do **** t be able to function
Disoriented diver: Guys I gotta head back up The Guys: You’re actually going down Disoriented diver: My bad The Guys: Now you’re going towards your right, not up, nor down Disoriented diver: thanks, heading back up...nnnow The Guys: You’re currently moving diagonally downwards Disoriented Diver: What IS this “up” anyways ?!
I am kind of confused beacause if the three semicircular canals give sensory information about all possible head positions, why do we need the utricle and saccule?
Very confusing explanations: Semicircular canals provide visual stabilization (called VOR) during day to day head motions, such as looking side to side in a grocery store. There's no VOR in the roll plane (Y axis) governed by semicircular canals. Vertical and horizontal head turns are governed by the semicircular canals, while translational VOR (forward, backward {car travel], upwards and downwards{elevator}) is governed by the utricle for eye stability in their respective orbits AND redundant body / postural positioning with the proprioceptive system. No known balance contributions (known yet) are rendered by the Saccule unless it's an organ of primacy in the supine position for pre-postural infancy. The video explanation of dizziness is completely wrong; rotational spin through the semicircular canals manifests in inertial LAG (endolymph is slower than initial acceleration of the spin causing the otoliths to move OPPOSITE the direction of stimulation). When the spin stops inertial lag of endolymph continues. This doesn't cause dizziness, it's the lack of management of this stimulus (inertial lag, catch up, latency) that results in the perception of dizziness. Both utricular organs and the VOR system deficits can lead to "dizziness" when their reflexive contributions AND CNS repression systems are aberrant or damaged. However, utricular input errors cause most commonly POSTURAL anomalies and imbalance, NOT primarily dizziness (exceptions: Meniere's, boat travel). Head motion provoked dizziness (head turns) = VOR dysfunction Body motion provoked dizziness (boat travel) = utricular dysfunction Vestibular rehab is IMPOSSIBLE if the treating professional does not understand these VERY important differences.

i found so endering the way the narrator got so excited while explaining everything. Thaks for the video.
I don't understand why Khan Academy can explain this concept in less than 10 minutes while my professor needs 2 hours.
No dude, it's because there is a lot more detail involved for them to test us on...
This is an overview and actual class is more detailed

Hilda Graham hahahaha lol great marketing skills
SlightlySaturated lectures are the worst. Just let me read and watch RUclips, I’ll come in and take the test.

I REALLY enjoyed this. Every minute too.
To me this shows the awesome design from a most wonderful Creator!
This design can not happen on its own.actually the creator is truly perfect.
@@WaniBilal-ul6db You are calling the vestibular system perfect in the face of imperfections. That is blasphemy in the face of the "perfect" creator.
You are so brilliant!!!! I thank you very much

Really great, thank you. Is there a part two of this though?
Awesome video! Thanks!
Thanks khan academy
Thank you very much. You explained it in a clear, precise and engaging way. Thanks a lot.👍
04:26 who else get emotional when she gets emotional about the crystals (:

you're a joy to listen to!!! thanks for the great review :)
That Little Stunt You Pulled At 3:44, Leaving That Bit Of Writing UnErased. Yeah, It Was Bugging Me.
thanks a lot for the clear explanation!! 😀

thanks a lot! made my life much easier :)
the human body is such an engineering perfection by nature, so simple but also so complicated
God is amazing
Thank you so much. Bless!
thank you so much!! The explanations were so easy to understand great use with examples and drawings!
well explained videos!!
شكرًا جزيلا thank you so much
nice drawing and concise explanation, gotta love Khan Academy
u explain it so well...it's really understandable! much thx
So nice but for me it's like a Télétoon with those drawings
That's so awesome!
Brilliant explanation. Thank you!
Great video. Thank you so much as always. Respect .
very well explained and easy to follow. Thank you!

What you explained about dizziness, can it also apply to one who just came off a lift (elevator)?
Thank you!
Wow nice video...thanks!!
nice drawings :D
There is so much science.
Well done
Good
:-) Dear Khan academy, can you do you one on peripheral vestibulopathy please?
awesome
is there any medication for off balance system
It’s amazing the me that with the jump in medical science people still believe this all happened by random chance not by intelligent design!
Love video but how can I keep crystals from moving in wrong direction to stop vertigo?
I'd love to know what program is used to create the presentation, thx in advance:)
so in bppv are the crystals from the otolithic organs? If so how are they causing dizziness in the SC canals? Are there hair cells in the SC canals? thanks
I believe BPPV results when crystals have been misplaced from the otolithic organs. That is why treatment includes particle repositioning manoeuvres, such as the Epley's manoeuvre.
love ur video, it was so cute:)
سبحان الله
i need to see these carbonated crystals
What is Loss of Inner ear vestibular balance sensitivity in both ears? Almost a complete loss..
I have oscillipia from a nerve being burned out due to otoxicity fro vancymycn and gentamycn. ^ yr **** is moving all around 24/7. No quality left in life. Can't do **** t be able to function
I’ve got hyperactive vestibular disorder! it sucks
When people shake their heads why does it make me feel dizzy by concentrating on them?
mirror neurons?
Thought they were filled with perilymph.
the way she talks reminds me someone
Soso from OITNB
the brain from arthur
from the princess in tangled
Kelly from The Office
Mia Khalifa
what exactly is the job of the utricle and saccule?
both deal with vertical orientation (gravity) and linear acceleration
this was 7 months ago lol. anyways thanks!
Not me spinning around my living room 😂😂😂
Ecellent
Disoriented diver: Guys I gotta head back up
The Guys: You’re actually going down
Disoriented diver: My bad
The Guys: Now you’re going towards your right, not up, nor down
Disoriented diver: thanks, heading back up...nnnow
The Guys: You’re currently moving diagonally downwards
Disoriented Diver: What IS this “up” anyways ?!
I am kind of confused beacause if the three semicircular canals give sensory information about all possible head positions, why do we need the utricle and saccule?
+Peter Arnold simple answer is that the semicircular canals sense angular acceleration while the utricle and saccule sense linear acceleration.
+stupidkidlol Alright, makes sense. Thank you for the answer.
Is it just me or the video is blur even at 720p?
I don't understand this very much. She explained the abnormality in last seconds very fast!!

Head motion provoked dizziness (head turns) = VOR dysfunction
Body motion provoked dizziness (boat travel) = utricular dysfunction
Vestibular rehab is IMPOSSIBLE if the treating professional does not understand these VERY important differences.
can you explain this to me again slowly, like im dumb
I can understand this 6-minute video AFTER I spent about 20 minutes watching this video from professor Fink:
ruclips.net/video/AKDkzqZZZlE/видео.html
Is it just me or the narrator's voice sounds awfully similar to Alex Dunphy from Modern Family? XD
I think the body position part is more useful for blind people cause non-blind folks can see what is their body position.
This is how you know that God has a sense of humor.
yea
Professor Daemicke is that you?
If a person is deaf, he finds it difficult to balance his body???
Any body here have experieced the dissociation?
Why did video just end?
Idk ig there was nothing left to say lol
Anyone here from Baku when a guy shatters someone’s vestibular system?
not for medical students, too basic
Well it gives you basics so you can have some overview, the rest of the information can be found in any anatomic textbook.
It's also very clearly labeled as "MCAT" - ie it's for prospective medical students, not medical students. For a basal level, this video is great.
The pronounciation isn't clear

This is awesome thanks!!
Amazing
