Structure of the Ear

To be able to care for the ear, it is necessary to understand its structure. The ear is divided into three main parts: the outer, the middle and the inner ear.

Functions of the Ears

The ears perform the following functions:

1. We use them for hearing; the outer ear which is like a funnel picks up sound or noise and is received by the ear drum. The ear drum in turn transmits the sound to the inner ear where it is relayed to the brain. In the brain, the sound is interpreted into a meaningful message. There are some tiny hairs at the entrance of the outer ear which prevent dust from entering the inner ear.

2. They help us to maintain our balance.
