My brain is protected inside my skull by cerebrospinal fluid which acts as a shock absorber. This cushions the brain from damage caused by everyday bumps or knocks.
This cushioning is needed because, inside my skull, my brain is soft and squishy – like ripe avocado or warm butter. If my head is suddenly hit against something hard, the brain may be ‘bounced’ against the inside of my skull, and brain tissue can be stretched or bruised. In serious cases, the brain may even bleed.
How could my brain get an injury?
The most common causes of injury to the brain are:
• car accidents
• bicycle accidents
• sporting accidents (eg a rugby tackle, or being hit by a cricket ball)
• being struck or hit by another person
• illness (eg meningitis or seizures)
• lack of oxygen (near-drowning or suffocation)
How can a brain injury make me feel?
People with brain injuries can have many symptoms. They may include:
• loss of memory
• inability to concentrate
• moodiness / irritability
• changes in behaviour or personality
Other effects of an injury depend on the part of the brain that is damaged. For example, problems with hand/eye coordination may happen if a particular part of the parietal lobe (area of the brain just behind the top of the head) is injured.
How can I keep my brain safe?
There are things I can do to protect my brain from injury. They include:
• wearing helmets for activities such as riding a bike or skateboarding
• always wearing a seatbelt in a car
• being careful in high or dangerous places where there is a risk of falling
This week we have 3 research tasks that you could complete;
1. Research and find five amazing facts about our brains?
2. Research into some of the medical conditions that can affect the brain?
3. Research the different parts of the brain and create a diagram to show these areas.
