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.

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!

You are so brilliant!!!! I thank you very much

Exceptionally well made video. Nice and simple, terrific drawings! Thank you!

Really great, thank you. Is there a part two of this though?

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!

Thanks for making all the content easier. very well explained.

I REALLY enjoyed this. Every minute too.

To me this shows the awesome design from a most wonderful Creator!

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.

Thank you so much. Bless!

thanks a lot! made my life much easier :)

That's so awesome!

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.

04:26 who else get emotional when she gets emotional about the crystals (:

Thank you very much. You explained it in a clear, precise and engaging way. Thanks a lot.👍

Awesome video! Thanks!

very well explained and easy to follow. Thank you!

Great video. Thank you so much as always. Respect .

thanks a lot for the clear explanation!! 😀

u explain it so well...it's really understandable! much thx

Brilliant explanation. Thank you!

well explained videos!!

you're a joy to listen to!!! thanks for the great review :)

nice drawing and concise explanation, gotta love Khan Academy

So nice but for me it's like a Télétoon with those drawings

شكرًا جزيلا thank you so much

This is awesome thanks!!

That Little Stunt You Pulled At 3:44, Leaving That Bit Of Writing UnErased. Yeah, It Was Bugging Me.

Wow nice video...thanks!!

the human body is such an engineering perfection by nature, so simple but also so complicated

thank you so much!! The explanations were so easy to understand great use with examples and drawings!

I'd love to know what program is used to create the presentation, thx in advance:)

is there any medication for off balance system

There is so much science.

:-) Dear Khan academy, can you do you one on peripheral vestibulopathy please?

awesome

nice drawings :D

Thanks khan academy

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?

Thank you!

What you explained about dizziness, can it also apply to one who just came off a lift (elevator)?

Well done

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

Amazing

When people shake their heads why does it make me feel dizzy by concentrating on them?

Thought they were filled with perilymph.

I’ve got hyperactive vestibular disorder! it sucks

Not me spinning around my living room 😂😂😂

Love video but how can I keep crystals from moving in wrong direction to stop vertigo?

Good

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

سبحان الله

Ecellent

Is it just me or the video is blur even at 720p?

i need to see these carbonated crystals

what exactly is the job of the utricle and saccule?

the way she talks reminds me someone

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?

I don't understand this very much. She explained the abnormality in last seconds very fast!!

This is how you know that God has a sense of humor.

Is it just me or the narrator's voice sounds awfully similar to Alex Dunphy from Modern Family? XD

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 ur video, it was so cute:)

Professor Daemicke is that you?

Any body here have experieced the dissociation?

I think the body position part is more useful for blind people cause non-blind folks can see what is their body position.

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 ?!

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.

not for medical students, too basic

Why did video just end?

If a person is deaf, he finds it difficult to balance his body???

Anyone here from Baku when a guy shatters someone’s vestibular system?

Bhai Hindi m hota to accha hota

The pronounciation isn't clear

That valley accent doesn't help at all..

Horrible video today with the new technology you can provide animation which wold make easier to understand
