Way of teaching is just what we want..just perfect ❤️👍

How our ears works? 😳 First there is a outer part pinna which we can touch it is used to collect all the sound waves and send it to the auditory canal which is used as a channel 💕...Next part is ear drum which is a transparent layer. It vibrates from a very small motion. it also separates inner ear from external ear.🧁 Then the middle part of ear comes. In this part there are three tiny bones which are called ossicles. Which vibrates and transfers sound waves to inner ear . It also amplify the sound. Amplification is needed because There is liquid in inner part and it needs to be vibrated at a high pressure. Ossicles can increase 20x in pressure. The three bones of ossicles are: First bone: Malleus 😶 Second bone: Incus 🧁 Third bone: Stapes 😜 Next is the inner part of the ear.... Here are semicircles three rings. This helps body to balance. 🤗 A snail shape structure called cochlea. The fluid vibrates in it. Cochlea has special cells which converts sound waves to electrical signals. Unless Sound waves are not converted to electrical signals. They don't reach our brain and we are not able to hear Sound. Then these electrical signals reaches are auditory nerve which helps sound waves to reach the brain and we are able to hear 😁. Because of Cochlea cells We can hear different sounds. They are sensitive for loudness and frequency and we can also tell when a sound is loud or soft and its frequency is high or low.This is how our ears work 😉

Made my studies so easier....really happy to understand the thing which i was so stressed about 😄

Being a medical student... I missed learning like this for a few years now 😂 kudos to you sir ✌️ you explained this wayyy better.

Ur way of teaching is outstanding.i really got a lot of help for my board exams

I wish all teachers were like you. Basically biology is not easy to learn and I personally think that a part of learning is motivation. Teacher needs to grasp students attention and motivate them. For brain studies it is a must to have a look at the anatomy of brain, touch it, divide it to understand its functions. It is a must to learn different cases of injuries and deficits of the brain to go deeper so we won't forget what the actual functions are.

I really loved it. It really helped me and the best part was your definition for outer ear.

I just want to say thank you so much for making this video!!! It has helped answer my questions about pressure within the ear. Also I really appreciate the enthusiasm and dedication to the animation and narration of the information. Just wonderful!!!

I'm pausing the video after every three mins to just say how comprehensive and simple ( yet amazingly decent ) it is. You're my fav teacher :)

Who i really liked your English accent it's not like actual indian accent which i fined so cringy and can't really understand as a foreigner but as a Indian your English was so undersdable and i really liked the way you thought thanks a lot man!

This video helped me to understand about ear clearly Thank you sir

Very informative and good animation. Just what I was looking for

Lift an amazing feelings inside me . It is a wonderful way to know about these information instead of traditional dull methods of learning . It also a great thing to give attention and feel thankful to all pleasant givings inside and around us ❤️‍🔥

"Who is the owner of your eyes and ears, the most precious of your members? From which workbench or shop did you obtain them? It is only your Sustainer that could give you them. It is He Who creates and raises you, and gave you them. In which case, there is no Sustainer but He, and the only one fit to be worshipped is He." Words - 429, by Said Nursi, (Qur'an, 10:31-2.)
