Structure of the Human Ear

[CelineFeibleman]

Thank you for putting so much time into these videos so that the information is clear and explained in a logical manor. Would love some more in-depth videos on sensory systems!

[Megha-ijeo]

Your way of teaching and notes of all lectures really impressed me a lot...😊😘❤👌Love from India

[kevinnguyen]

Yooo these videos are going to carry me into med school. Great work!

[tahirsheikh]

Thank you for putting in the time to do this!

Learned more in a 12 minute video than I did reading 25 pages in my textbook.

I am just wondering, what do u study?

[techiekunalmishra]

You made ear simple but it's too simple

[bashirchedrawee]

Hello, you say @3:30 that the force within the eardrum is larger according to pascals principle of P1=P2===> therefore since the area of the eardrum is smaller then the force should be smaller. Also we know that because the area is smaller the velocity is also less due to resistance, another reason why the force is less. Studying for MCAT now and wondering. thanks so much

[anumishra]

Thank u so much from India. Your lectures are very helpful.These lectures helped me in visualising biology

[robbybarton]

thank you so much for your lectures. i have learnt so much as well as it has helped me prepare for my exams!

Everyone who talks about the inner ear has his own idea of how it works! I think you are wrong in emphasising a 'pressure wave'. Firstly, you say that a pressure wave cannot travel in a liquid, but this is wrong - sound travels very well in water, as a pressure wave. A fluid cannot support a transverse wave. it's just that the medium is very stiff, but it is compressible. You then talk of the pressure wave causing depolarisation, but this is not right. The cilia sense movement of the membrane not the fluid pressure. Very importantly, the cochlea works using not pressure waves but transverse waves set up across the membrane between two chambers which propagate in a very special way, and the round window allows this transverse wave to be set up by allowing movement of the membrane to cause fluid displacement, though some of that displacement progresses to the apex depending on frequency..

Can you clarify if both stereocilia (hair cells) in the semicircular canals and the ones in the coclea (specifically organ of corti) act in the same way. Both will have K+ channels and Ca2+ that will hyperpolarize and depolarize, but both do not cause an actual Action Potential correct? Also, how does the basilar and tempanic membranes work? Thank you!

[jennifersharpe]

It would be great if you explained the endolymph with K+ and effect of K+ on steriocilia with the cadherin (tip links) stretching of the kinocillium and where the K+ flows (toward the basilar membrane) depolarizing and how we get the K+ back out or hyperpolarized

[haricohly]

FYI: the IHC or OHC do not have microvilli but rather stereocilia as stereocilia are motile and microvilli are not motile.

woow ur videos was sooo educating and enlightening and informative ....it also helped me prepare for a seminar at school clear explanation ....very useful

[CurveLearningNatures]

Having had the strangest experiences with my ears over the last few years, this video was extremely helpful.  Thank you.

Thanks for the teaching keep it up 👆 🙏🙏👌❤️

Brilliant, Thank you from an Med student learning ENT
