HEAD INJURIES -
In times of war, soldiers use special helmets to protect their heads. While driving a scooter, the riders often wear helmets to protect heads against any injury. In many cities, the government has made the helmets compulsory for riders. Do you know why the protection of the head is necessary?
The most important part of our body, the brain, is located in the cranium under the protection of bones. The human brain is divided into three main parts - the cerebrum, the cerebellum, and medulla oblongata. It controls all the important functions of the body - sight, taste, smell, hearing, touch, movements, memory, speech, etc. Any damage to the brain can disturb the proper body functioning.
Our brain is protected by the thick bone of the skull. Further, a shock absorbing fluid cushions it against the blows bumps. But if the blow is sharp or hard enough, it can injure the skull. Thus to protect the brain from injuries, it is essential to first protect the head.
Now the question arises, what may be the consequences of head injuries?
A severe head injury due to an accident may cause brain hemorrhage which eventually may lead to death. The injury may damage the memory unit of the brain by which a man can lose memory, temporarily or permanently. It has been often seen that after having a severe injury of head, people remain in the coma for long periods.
If the brain tissues are damaged, it may give rise to multiple sclerosis. Parkinson's disease is caused by a disorder of brain chemistry which may result due to a head injury. Brain injury may cause aphasia, a serious disorder of thought and communication. Apart from these effects, many other disabling conditions can be generated by head injuries.
It is, therefore, essential to protect the head against injuries.
