The Ear

All about the ear.

Introduction

Have you ever thought of how the ear works for us to help us be able to hear sounds , why the ear exists, and many more? Well, I became really curious about that so I did a small research about it and found out loads of interesting informations so keep on reading if you are interested in what I am saying. Lets start!

Structure


Basically, the ear has 3 different parts and the first one is the outer ear (Pinna). This part is the part we can see, can touch, and can put ear piercings on. Pinna’s job is to collect all the sounds from the outside. Second is the middle ear (Ossicles). There is 3 bones that connects from the eardrum to the inner ear. In here, the sound wave turns into a mechanical vibration by the sound waves hitting the eardrum and the effect of this is that the ossicles will also start to move because of the eardrum ‘s vibration. Last but not the least is the inner ear (Cochlea). To explain this part’s step in detail, Cochlea that is shaped like a snail and has 2 liquids (endolymph and perilymph) sends electrical signals to the brain to indicate what type of sounds we are hearing.

Balance

Our ears help us with many things but one of the most helpful thing of all time is that ears help us have balance in our body which enable us to walk, eat, sleep, do anything you want to do. The ear has two types of balance and the first one I am going to tell you is the “Static Balance”. This balance makes us feel the gravity which basically holds us upright and not fall to the left while walking.The other one is called “Dynamic Balance” that help us feel the speed we are going.This balance make us feel the speed and can tell our minds to go faster or slower.

Hearing

One of the most noticeable thing that ears enable us to do is the hearing sense. When there is sound, sound waves go through the ear canal. At the end, they will reach the eardrum where the sound waves is passed on to ossicles.Than, the sound waves go to a snail shaped inner ear also called a cochlea. Inside the cochlea, there are thousands of tiny hair cells that changes the vibration into electrical signals and sends this signal to the brain. When this hair cell is damaged, it will cause loss of hearing and ringing in the ear (tinnitus).

Thank you for reading, I hope you understood how the ear works and what exactly the ear helps us to do in our daily life. Now that you know that the ear is doing a lot of work for you, let’s try not damage them because it would be extremely hard without the ear functioning for us!
