the X-axis (horizontal axis) is also called the lateral semicircular duct and corresponds to saying "No". Y-axis (vertical axis) : Anterior semicircular duct : saying "Yes" Z- Axis : Posterior semicircular duct : tilting your head laterally Your lectures helps alot. Thank-you Prof. Fink.

professorfink My pleasure Prof. Fink

been in family medicine for 30 years - your lectures are wonderful - you are a very gifted teacher

You're amazing. I've never been this mentally stimulated in a lecture before. Thank you!

i just paused the video to say YOU ARE GREAT !! I wish i had teachers like you in my school, i am here because i was trying to find something really useful that would actually make me understand what happens in the vestibular apparatus.. i was trying to learn from books but nothing s better than these kind of videos you make. Thank you very much !!!!

Thank you so much. I couldn't imagine trying to pass physiology without your lectures. You are a great professor!

I used these videos to make it through my A & P class, then I went back and used them again to get through my perception and sensation class in my junior year of college, then again in my anatomy of speech and hearing class...!!! thank you, 10 times over!!

everything is so crystal clear! why cant i have lecturers like youuuuuuuu!

Thank you Professor Fink for the wonderful and FREE lectures which are so helpful and engaging. I was a teacher for many years and I am so glad we have resources like you online for aspiring health care professionals like myself. I'm currently taking Anatomy and Physiology online and feel with videos like these that I've made an excellent choice. I feel very spoiled to be able to study when I want, where I want and by whom (professors like you) to really make things clear, fun, interesting, engaging and easy to understand. Thank you so very much for your hard work and sharing it so freely.

Thank you, Thomas, for your kind words. My sincere Best Wishes for your Success!

Great!!! Please, try to continuous making these videos. I am from Ecuador and I can learn better than my professors explained in the medical school.

PROFESSOR I love your videos!! I wish you could teach my classes!! You make it easy to follow. Your humors examples help stick these concepts into long term memory.

Great Teacher!!!! I can understand and REMEMBER.... I am so thankful for these videos!!!

This professor is awesome. So easy to listen and absorb what he's teaching.

My Anatomy professor followed your style of teaching. Thank you Sir :)

What have you become now 😢 ?

A stereo effect as there are two separate complete sensors sending information simultaneously to command central. A gymnast can utilize the system to control muscles to adapt to required movements. Combined with sight, sound, touch there are a lot of inputs for the processor to assimilate instantly to activate proper muscle skeletal systems. Imagine the design development stage of this project.

Thank you the great teacher

Well said. I watch all of his video. He is one gifted teacher

I wish I had this guy as my prof - he is very clear & makes it quite easy to understand. Thank you!

great as always....very clear and easy

Thanks! Great upload Prof!

You are so funny !! - thank you soo much !! I’ve been looking for this info in those thick textbooks 😓 and none of them explained it better than you do !! - excellent video uncle ! 😁😁

You are truly amazing!! Really helped me understand it! Wish I had a teacher like you! Great job :)

thanks too much professor,your explantation is amazing ,really thank you for your effort

this is fantastic!

WOWWWWW That is the best lecture Ive had :) thx so much!!!!!

favorite teacher!

Great lesson! Thank you Pr.

wow. your class was not boring. I had a lot of fun. thanks for your time. excellent job sir

Thanks a lot.

that was good our 'old' friend the thalumas!

Thanks for this social service..

Thanks a lot. You are a great lecturer. 😃😃

thanks a lot prof easy way and simple in presentation

Thank you so much !!!

Yous Sir are amazing!

Muy buena la clase profesor, me fascino la forma como enseña....

Thank you Professor for your great lecture especially for me as a person with vertigo. Hoping by watching more videos learn more and learn more. We need petiole like .you.

Awesome!

thank you!

Regarding the Otolith... What about people getting caught in an avalanche? I recall that they are often not able to tell what is up and down?

Noice professor fink, very noice

Amazing

thank you

thank u

this is talent

professor about the otolith brake acceleration thing i though it was inertia or it is otoliths that cause inertia

Professor fink where can i have those notes that you use during your classes on a pdf or a doc ?!

Thank you, Professor Fink for the lecture, but I believe that there is a mistake in the movement of endolymph inside semicircular canals. The fluid will move opposite to the direction of the head rotate.

Also, in zero gravity of outer space, the stone in the Utricle Saccule would be thrust against the hairs along the walls whenever an astronaut’s head moved or turned suddenly in the opposite direction (like when accelerating, braking or turning in a car). Wouldn’t this give the astronaut a sense of gravity in that particular direction?

@Individual Perspective *IP* What do you mean? Use your schooling and try to be an example of intelligent discussion. Come strong, because I know my stuff!

Where can I access these diagrams. Which books are they taken from?

Nice teacher

Sir ...so the endolymph rotates in the opposite direction of motion ...so do hair cells

Hey professor, I found a mistake in this lecture. Due to its' viscosity, the endolymph moves in a direction opposite that of the linear acceleration of the head (i.e a clockwise rotation of the head would result in the counterclockwise movement of the endolymph, leading to a deflection of the cupula in a direction opposite to that of the direction of head movement...at minute 7 you seem to posit the opposite)

Your students are so lucky

sir i was trying to get your notes are your notes available with your remarks and if yes please tell me which website should i go

Very good lectute. But hair cells in the utricle and sacule located in special places, called macula (spot) of utricle and macula of saccule. They are approximatly 33000 and 18000 respectively. And nothing about hair cells of ampullae (crista ampullaris).

Hair cells in ampullae do exist and each of them contains appr. 50 - 150 stereocilia and 1 kinocilium.

Amazing lecture, as always! Thanks a lot! @professorfink, how big are those structures in humans? (otoliths, vestibular apparatus, cochlea)

thanks for the information professor, but I want to ask something, if our head is moving either upward backward or like saying no, or tilting our head, did both of the semisircular canal and utricle sacule work together or just one of them? sorry for my bad english, i hope you understand that. thank you sir

The semicircular canal AND the utricle & saccule are ALL continuously sending information to the Brain.

+professorfink so, if I make a conclusion, the semisircular canal is more work to give a brain a signal then give another signal to other organs like eye to make a nystagmus, or proprioreceptor like muscle to balance our movement, and the utricle and sacule is to tell our brain how is our position and our movement, is it correct prof? sorry if I make it a little bit confused.

@@devangeesoni4753 Hi Devangee! Yes! The Lecture Outline contains ALL the line drawings and they are all downloadable & printable.

technically, its' the hair cells in the crista ampullaris of the semicircular canals depolarizing, not the SCC itself because its not completely comprised of hair cells.

Im sorry to inform you professor but otolith membrane (utricle and saccule) is responsible for linear movement, meaning when you walking, your utricle hair cells are depolorizing when you are jumping your saccule hair cells are depolorizing. when you are rotating, your semisircular canals are depolorizing. Great work btw

plz sir we need your notes

damn feke! Yous Good Prof!! Yous Good! #BWA

The lesson is brillant and pf Fink is great, but in my opinion he made an error explaining the behavior of the otolith when a subject is moving down. Ototlith might go up, not down, because of the difference of density btw Caco3 and endolymph. But I agree, it is a detail...
