The Human Ear and Nose: Structure, Function and Care
The Ear
You all know how important your ears are, especially for hearing. Therefore, they require good care. The outer ear is the part seen from the outside, the middle and the Inner parts are covered by skin and muscle.
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.
Care of the Ear
One important material for ear care is the cotton bud.
Ways of taking care of the Ear
1. The outer ear should always be washed carefully and dried with a towel.
2. If objects or insects enter the ear, it is necessary to remove them immediately either by putting a few drops of warm water or drops of olive oil into the ear.
3. When girls are born, their ears are pierced and small gold earrings are put in their ears. Do not put on very heavy earrings that could cut your outer ears. .
4. There are some wax inside the ear which protects and prevents dirt and small objects from entering the ears. When the wax reaches the outer ear it should be removed very carefully with fluffy cotton buds. Never use match stick, pin or pen cover as they can damage the ear drum.
5. Water should not be allowed to enter the ear and remain there as this will disturb the eardrum and block the sound passage.
Prevention and control of Ear problems
1. When insects or other objects enter the ear and are not easily removed with water or simple liquid or cotton buds, see a qualified medical doctor to avoid serious damage to the eardrum. Serious ear damage may cause deafness.
2. When the ear is swollen or is bringing out pus, see the doctor immediately.
