The function of the inner ear is no less important than the outer and middle ear. Like the rest of the ear, the inner ear has a function to listen to sound. But apart from that, the inner ear also plays an important role in maintaining the balance of your body
The ear is divided into 3 main parts, namely the outer, middle, and inner. The outer ear consists of the ear canal and the auricle, while the middle ear consists of 3 small bones, namely the malleus, incus, and stapes.
The inner ear is the innermost component of your ear which is often also called the labyrinth because of its complex shape and function. The following is a more detailed explanation of the function of the inner ear.
Main Functions of the Inner Ear
The inner ear has 2 main functions, namely:
Hear the sound
The main part of the inner ear is the cochlea, or it can also be called the cochlea, because of its similar shape. Inside the cochlear canal there is fluid that transmits sound vibrations and the organ of Corti which functions as a receiver for these sound vibration signals.
There are several processes that occur from the outer ear to the inside so that a person can hear and understand sounds, including:
- Sound waves will enter through the earlobe and be transmitted to the eardrum.
- Eardrum vibrates and sound travels to 3 small bones in the middle ear.
- This movement of the middle ear pushes sound waves into the middle ear and causes vibrations in the fluid in the cochlea.
- The vibrations of the fluid in the cochlea will be received by the organ of Corti.
- The tiny hairs in the organ of Corti convert sound waves into electrical signals.
- The electrical signal is sent to the brain via the auditory nerve, so we can understand what sound we hear.
Organic balance of the body
In the inner ear there is a semicircular section filled with endolymph fluid and motion sensors that resemble fine hairs. This section is known as the semicircular canal.
The semicircular canals are connected by sac-like structures, namely the utricle and saccule which also have motion sensors. These three organs both play a role in maintaining the balance of your body.
When your body moves, the fluid in this organ will also shift so that it moves the fine hairs in it. After that, the motion and balance sensors will send messages to the brain to tell your body to stay balanced.
The brain will respond to this by giving commands to muscles throughout the body to coordinate in such a way that the body is in a state of balance.
This system allows you to remain stable and balanced when you are in an elevator going up and down or sitting quietly in a car that is moving forward or backward.
The function of the inner ear is rarely realized. In fact, the function of the inner ear can be said to be the key to the sense of hearing and the function of your body's balance. In addition to its small size, you really can't see it directly because it's so deep.
However, keep in mind that without a he althy outer ear and middle ear, the inner ear cannot function properly either. Therefore, take care of your overall ear he alth.
The most common and easy way is to keep the ears clean. Earwax that builds up in the ear canal can affect hearing, increase the risk of developing external ear canal infections, and injure the eardrum.
In addition, avoid listening to songs or movies with very loud sounds, especially when wearing earphones. If you are in an area that is constantly noisy, wear ear protection that can reduce noise from outside.
If there is a complaint in the ear, such as hearing loss, whether accompanied by a balance disorder or not, you should immediately consult a doctor to get an examination and proper treatment.
