The ear and its function

Three parts of the ear work together to pass noise from external sources through your ear to your brain for information processing. The three sections are known as; the inner ear, the middle ear, the outer ear. The inner ear is made up of the cochlea, the auditory nerve, and the brain. The middle ear consists of the middle ear bones called the ossicles (malleus, incus, stapes). The outer ear includes the pinna, the ear canal, and the eardrum.

 

How the ear works?

The sound waves travel 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.
