Ever thought of life without ears!!! Of course, there are people who are leading their life without ears but just think of a movement if your ear stops working. You will surely miss the chirping sounds of birds, soothing sound of wind, refreshing sounds of silent music and so on. Moreover, you will find it difficult to understand what people say and how is your surrounding working. Surely, ear provides lot more than just hearing.

Ear is the only organ that help us in understanding our surrounding by listening to them. Many a times we fail to understand the importance of this vital part of our body. Ear continues working even while you are asleep. Let us learn something about ear and try to give a little care to this auditory organ of our body.

Middle ear is a small air-filled space which is present in the inner side of the eardrum. There are three tiny bones present in this part, known as ossicles. These bones are named according to their appearances: hammer, anvil and stirrup. Sound waves coming through outer ear moves the eardrum and these bones also move passing the vibration to the oval shaped window of the cochlea. The hammer bone lies close to the ear drum. When the sound waves move the eardrum, the hammer bone is automatically shaken. This vibration passes to the anvil and the stirrup bone which are also attached to the cochlea. Due to the size difference between the eardrum and the oval window, the middle ear can efficiently change the vibrations from the outside air to the watery fluid inside the cochlea.

The cochlea contains fluid that can move and bend the hairs present outside the cells. These hairs are very tiny and each ear has more than 17,000 hair cells. The inner hair cells create an electrical impulse which is passed along the auditory nerve to the brain. The outer tiny muscle cells react to the vibrations in the fluid by trembling and shaking. This is how we get stronger and clearer vibrations for the tiny inner hair cells. Rest of the work is accomplished by the brain and we start hearing.
