The human ear - a magnificent organ

The human ear is an advanced and very sensitive organ of the body. The function of the ear is to transmit and transduce sound to the brain through the parts of the ear: the outer ear, the middle ear and the inner ear.

But what other sensory functions do the ears provide? The major task function of the ear is of course to detect, transmit and transduce sound. However, that is not its only function. Another very important function of the ear is to maintain our sense of balance.

The parts of the ear and their function

The best way to describe the functioning of the ear is to describe the path which the sound waves take on their way through the ear. In the video you can see the journey of the sound waves through the ear.

The sound waves travel through the various parts of the ear: from the outer ear and in through the auditory canal, causing the eardrum, or tympanic membrane, to vibrate. This, in turn, causes the three small bones, known as the ossicles, or the hammer, the anvil and the stirrup, in the middle ear to move. The vibrations move via the oval window through the fluid in the cochlea in the inner ear, stimulating thousands of tiny hair cells. This results in the transformation of the vibrations into electrical impulses finally perceived by the brain as sound.

When this process is not functioning correctly, hearing loss can occur. There are different reasons for its occurrence. Read more facts about hearing loss  and the causes of hearing loss.

The ear consists of many small ear parts, but can be divided into three major parts of the ear:
