Anatomy | Physiology of the Semicircular Canals

[@toxinak3432]

You let audience learn a lot with small number of slides. This is an indicator of good teaching skill.

[@Awesomeisme7000]

That is the complete opposite of what my teacher does...

[@Damnnthatscrazy]

That intro was threatening. Very nice

[@zack_120]

5:36 - Probably before the hair tufts sweep to the right or left when head turns, they must first go briefly to the opposite direction which is perceived as such, right?

[@husseinabd-alraheem8618]

these videos regarding the vestibular apparatus were super helpful

[@inderamohanbisht4998]

Excellent Teaching. Congratulations. Keep the good service.❤

[@hdh2179]

amazing job so clearly explained thank youuu

[@samirajamshidishal2558]

you made it so easy to understand. Thank You so much.

[@ehnachan4271]

thanks for this! great explanation!

[@emilychance1426]

Thanks so much for this info! I'm currently dealing with vertigo and this helped me understand what's going on ❤️

[@carlyruiz1997]

Regarding de movement of the endolymph in the CSC, whether is excitation or inhibition it is important to know of which ear we are talking about. Great lecture!

[@user-go1sw9mx1r]

Excellent presentation.

[@sindhurekha8027]

Best video ever.... Wow. Thank you sir.

[@gammmm6814]

very clear explanation! Thank you so much💗

[@anikajaved4885]

Thanks , that's really helped a lot

[@latikasharma08]

Very well explained.

[@lemia402]

Thank you so much for this video! Very put together :)

[@CatalystUniversity]

Thank you and no problem!

[@raquelorenzoo]

Amazing videos!!! Very helpful, thanks!!!,

[@CatalystUniversity]

Thank you for the kind words.

[@svivekvardhan66]

tomorrow is my exam lmao yeah it was great to recap

[@TswelosTales]

thank you

[@vinitaarajakumar8972]

Thank you very much for this! So the vestibula and ampulla works together right? For example when the head is tilted forward like in nodding yes, then both crista and vestibula work together for the balance in that head position?

[@ashishrobertsamuelahne2188]

Thanks for great effort... For u shared a large knowledge

[@binahamed]

Anterior and posterior semicircular canals of opposite sides work in unison. It detects motion neither in true frontal or true coronal planes

[@olufemisylvester7440]

Does the anterior semicircular canal, utricle and saccule detect the same thing when it comes to head flexion and extension? I'm confused.

[@beastboyanthony]

To my understanding, the utricle (horizontal) and saccule (vertical) detect linear acceleration/deceleration whereas anterior semicircular canal detects rotation in the sagittal plane. Obviously there's some overlap

[@SteveInSunnyCA]

Your diagrams and explanations were excellent with one glaring exception. I’m not a doctor, but I think you will acknowledge that when the head turns, the fluid DOES NOT turn due to inertia. The canals turn and it’s the RELATIVE motion between the turning canals and the stationary fluid that is sensed by the body. I watched your video, and many others on the inner ear, trying to get the answer to another question that you may be able to answer. I notice that the three semicircular canals are not exactly mutually perpendicular. The anterior canal leans in about 10 degrees, or at about 80 degrees relative to the other canals. This would cause crosstalk and confusion in the information from the canals. Is there a valid reason for this arrangement? Did nature screw up? Thanks, Steve Hines

[@senserave]

Great way to learn. Great.

[@guillermodozal7166]

If I may ask, are the vestibules at the anatomical coronal plane?

[@namu_love]

is it not like, the horizontal responds to motion in the vertical axis ? that is the canal in right angle to the axis of motion is stimulated more? my book says so and im confused now...

[@nursebeltuseebong]

Thanks for teaching

[@mukulgidney]

Finally a good explanation

[@AmitisL]

Very helpful , thank you

[@محمدطلال-ض4ك]

Thank you for the video it helped me A lot

[@kaylavazquez8968]

wait so the baseline firing rate for the hair cells are high then right?

[@yankeedoodle2801]

Question, as our head moves the liquid in the vestibular system flows causing haircells to bend in ampulla and Maculae , and nerve impulses are sent to the brain. But the fluid is not in sync with the labyrinth because of inertia. So i am wondering if there's a latency of this type of signal transmission? How does our brain compensate this delay?

[@justastrawberrymonst]

Great video!!

[@LanNguyen-iu3oe]

awesome pictures and video! thank you so much!

[@revenanths4039]

Can u pls tell me The answer of The below Mentioned Question ? why Patient with acute unilateral Vestibular Lesion Experience Spontaneous Nystagmus?

[@sameerapinky2995]

Very helpful for clear concept ,,,,,,,thank you so much

[@CatalystUniversity]

No problem!

[@lordbishopkingmakercaraniu4118]

If anyones wondering why fluid moves opposite to direction of rotation. Simple physics Every action has an equal and opposite reaction

[@cj-cv7zv]

every action FORCE has an equal and opposite reaction FORCE. at least state the theorem in full 🙄

[@cj-cv7zv]

Also... it's just inertia, not Newton 3 :p

[@Dmplivemail]

Terrific content. Keep it up

[@КаурТаджвір]

What is ampullary crest ?could you tell .

[@doctormaryanne.]

Hello. Good day. I do not understand what you mean by acceleration to the left. Does left mean to the left hand side ???

[@FzSh-nj1li]

Thanks🙏

[@Thrynish]

Thank you so much!

[@rimshakhalid9007]

By this video I understand alot thanks alot

[@CatalystUniversity]

You're welcome!

[@RK-zi9fv]

Why is the direction of head movement and endolymph opposite? Isn't it the same due to inertia??

[@aasifamin5881]

yes

[@sheemaawan964]

hats off.

[@stephinabraham1117]

Those who disliked did it cuz they finally got it

[@medzac8794]

Great 😇

[@nazariiromaniuk2078]

Amazing and very helpful videos!!! You may have misspoken about superior and posterior semisircular canals detection of movements... it`s should be the other way about, isn't it?

[@anujjain5807]

Nah!He was right

[@aa-sg8yp]

The anatomical structure of the cupula is not presented properly

[@armoniammulatu8044]

[@areeba466]

Does the anterior semicircular canal, utricle and saccule detect the same thing when it comes to head flexion and extension? I'm confused.

[@mukulgidney]

Same doubt

[@enaskamal6544]

Utricle and saccule detect linear acceleration _Static balance But the 3 semicircular canals detect rotation around 3 axis so detect Angular acceleration _Kinetic balance

[@PureDoLee]

Thank you so much!
