Thanks that amazing brain of yours for your uncontrolled curiosity. Not only does this wrinkly mess of grey matter control all your body's automatic functions (breathing, blinking, food processing, the breathing of your heart), but it also empowers you to laugh, cry, create, dream, score a three-pointer in basketball, learn, paint, beat you sister at Mario Kart and ask questions. The brain is the master of your nervous system and the source of your personality. No other organ in nature is as mysterious.
What exactly is between my ears, anyway?
One of our body's largest organ, your brain is three pounds (1.3 kg) of fat and proteins condensed in amass with a tofu-like textures. Its contents come in two colors.
1. Gray matter : your brain contains about 100 billion nerve cells. Called neurons, they make up your brain's "gray matter".
2. White matter : your nervous communicate with one another by sending electrical signal and formatting chemical connections in a network of nerve fibres called dendrites and axons, which form your brains white matter. This communication between neurons is what is responsible for your every thought, memory, movement and automatic bodily function.
How much of my body's energy does my brain use??
The electrical messages bouncing across your at any given time outnumber the messages zipping through the world's telecommunications networks.All that activity requires enough electricity to power a dim tube light, that might not sound like much until you consider the brain uses 20 percent of the body's energy but is only about 2 percent of its weight.
What protects my brain from injury? ??
Our brains is a delicate organ that needs all the protection it can get. That thick skull of yours is it's first line of defense (being boneheaded is a good thing!) followed by three sturdy membrane called meninges. Fluid fill the gaps between these membranes, cushioning the brain from impacts. A special "blood-brain barrier" made of special cells acts like a security perimeter in the brains circulatory system, and keeps out anything that might contaminate your sensitive network of neurons.
Whenever you get in trouble for doing something totally lame brained blame your lame brain. It hasn't finished developmenting yet. Scientists discovered that the white matter connecting your frontal lobe---which control your decision making process to the rest of the brain isn't fully formed until you reach yourid 20s .In other words, your center of good judgement isn't fully wired into your brain yet .
Why we use only 10 percent of our brains ??
It's a reasoning idea for everyone who thinks they have superpowers or hidden artists talents: we would accomplish amazing facts if we could just tap into our unused reserved of gray matter. It's also a total myth. We use nearly every parts of our brain all the time. Even a simple activity like brushing your teeth, walking toward the toothbrush .Squeezing out just enough toothpaste, keeping track of which teeth you have cleaned as you brush away -activates a small electrical storm across your brain as the various lobes, cortices, and cerebellum work together to brush, rinse, split, and remember to floss, the activity in your brain never stops, even when you sleep.
Q. How can I protect my BRAIN??
A. To wear a helmet, without smoking, to eat well, to exercise our body, to exercise with mind.
