[@hadiabatool5628]

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 😉

[@margomoby684]

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.

[@rifahfariha1192]

Can't the atheists see the complexity of our body's systems.. how can it come by coincidence, of course it has a designer لا الاه الا الله محمد رسول الله

Zak Zedd who designed the designer that designed us then?

[@zakzedd9944]

@@learnlaw1363 The designer if he had a designer, it will become a cycle of designers, if I tell you the designer is created by X, you'll tell me again and who created the X.. that's why you shall see the complexity of our systems, or of cosmology, or biology or the zoologie or anything in this world, the more you study about it you'll find lot of complexity in it.. and you'd be a fool if you believed that all of that harmony came from coincidence, or just by the nature
