Structure and Function of EAR (MORE THAN HEARING)

- In this biology video in Hindi we explained the structure and function of human ear. Human ears do several tasks. Some of the most important are hearing and making balance of the body.
Human ear consists of the following parts.
1) Auricle or pinna : It is the outermost part of the ear. It collects sound and sends into the auditory canal.
2) Auditory canal : It is the hole of the ear. Sound propagates here and reaches the ear drum.
3) Ear drum : It is a membrane where auditory canal ends. Ear drum oscillates when sound wave incidents on it.
4) Ossicles : these are the bones connecting ear drum and the cochlea. There are three bones there. First bone is malleus, second one is incus and the third one is called stapes. Stapes is the smallest and the lightest bone in our body. When ear drum oscillates, these three bones alo oscillate.
5) Cochlea : This is a fluid-filled chamber having auditory sensory parts called hair cells. These hair cells contain hair-like structure called stereocilia.
When the fluid inside the cochlea undulates due to the vibration in it, the stereocilia oscillate and release ion into the body of the hair cell. This leads to the formation of the neurotransmitters in the hair cell.
These neurotransmitters bind with the nerve below it and signal is propagated to the brain and perception of hearing is produced.
6) Vestibular system : It is attached with the cochlea. It is having three semicircular fluid filled canals. This system can detect the angular position. It helps maintaining our body-balance.
7) Eustechian tube : It is a tube connecting the ear drum with the nasopharynx. It maintains the air pressure inside.

Aap sir kuchh to unique hai Jo mere ko video dekhne ke liye aakarshit kar teta h ❤❤❤
Bohat khoob. Mere Allah ki kia shan ha. Itna complex structure or kam me high accuracy 🤔. And as well good way to explanation 👍
Very useful video thanku so much sir
Thanks sir for understanding difficult topic in simple language you deserve in millions
Thanks sir , app sa pura 10th biology padha huuuu, Dhanyabad 😊😊😊
Science made our life so remarkable
Thank you So much Sir 🙂🙏🙏
Itna axa samjhane ke liye thank you sir
Thank you so much Sir ji your teaching skill is really indescribable !!!
Sir Plzz have a video on:- Why the ray of light is visible when electricity is passed through very low pressure & at high voltage, what's actually happens at quantam level? This doubt is as per cathode ray exp.
The thing is
Inside the cathode ray tube the electrons of atoms of gas draws energy from the flowing current. Thus they become exited and they release electromegnetic waves (lights) in order to go back to thier orbit( low energy state).
Best information
Thank you 😊
Sir sass lene me nose ka kya kya rule hai uske uper ekk video banado ❤ Topic -Nose

"Why the electric current produces magnetic field when it flows through any conductor "
Sir please answer it
When I asked this to any one and my teacher they only say that "this is the property of conductor"
Being a student of 9th standard, whenever electric current is passed through a substance, it produces magnetic effect due to electromagnetic.
Thank you so much sir ji 🙏👍
thanks❤❤❤
Thanks ❤
Deep explain
Subhanallah allah ke qudrat
Sir nursing ki anatomy physiology bhi padaaye please ❤
Content ko quality ke comparasion se bahut kam likes he, logi ko kuch kniwledge mile to uska regards jarur karna chahiye
Sir aap fir se ek baar neurons ke baare me bata dijiye
Usme ye ki ...
Kyu jb koi apna touch krta hai to achha lgta hai lekin agr koi anjaan aapko touch kre to aapko bura lagta hai
Ye brain kaise achhe aur bure ko kaise differentiate krta hai
Brain and neuron has no distinctive role there.
Your mind decides - ‘apna’ and ‘paraya’.

Thankyou sir
thanks a lot sir for this video
how do you explain every subject so beautifully?!
were you a pcmb student sir??
Class 9 and 10 Kai baki science bio chapter ko bhi start krai sir
???
Fir se???
Kyun?
Sir I request you to please open the link of unavailable videos of your channel particularly 9 and 10 class
There is no unavailable video.
I never saved anything to sell.
I distribute everything...
🙏
Eye ki bhi ase hi video bnalo
Thank you sir.ek bar cochlea ke internal parts pe bhi video bana dijie sir❤
B
1st view tha but video khtm hone ke baad comment Kiya
Sir a doubt please make a video on it
Electricity we know that
V=W/q and q=i×t
So V=W/i×t
V is inversely proportional to i but ohm's law says V is directly proportional to I
What is truth
Sir please explain
❤❤❤
How are you sir ji 🤗❤️
Good
Sir brain but in detail
Brain ka video dekh liya aapne???
Jo bataya gaya hai, usse pare kya janna hai - topic bataiye.
Sir 12th ka bhi padhaye
Fir se?
Good afternoon sir
Fine dear
Sir please make
6:04 a detailed Explanation video on Eustachian Tube, How it Connected to nasal pharynx And How it Effects our ears as when I inhale air From my nose my ear sense like hollow there was a incident happens with me ,my friend made a thin paper cone and placed in the my ear 8 months before, Doctor had given me some antibiotics but now this is happening after 8 month of that incident Although my ear is functioning well except Feeling like hollow when I inhale air ,these days as I am suffering from cough may be this is happening due to present of cough, If you know about it why this is happening and What could be the reason Please tell me if not then No problem 😔
And please make a video on Function of Eustachian tube
And
Thank you 🙂🙏🙏🙏 for providing such an informative video on Different topics for us
Description bahut jaruri hai
Sir on history of calculus
Sir please sence organ nose ko le kar ak video dije ...
Sir what is chemoreceptors?
Please explain
