Facts about the brain

The brain's fascinating and we still don't know enough about it, but we do know lots of facts which might actually be quite useful for Trivial Pursuit or pub quizzes. We know it's the consistency of porridge and we know it weighs about three pounds in weight. It is one of the longest organs we have. 75% of the brain is water, yet it still takes longer than any other organ to develop when we were in the womb. We know there are 100 billion neurons in the brain or wires, and that they are talking to at least 10,000 other neurons at a time. That equates to one quadrillion communications going on in your brain at any one time. The neurons give out chemicals called neurotransmitters. At any second in your brain, there are 100,000 chemicals that are being released to each neuron. We know we have 100 billion neurons in our brain and they release chemicals called neurotransmitters. Every second, 100,000 chemicals are being released into your brain.

The brain loves oxygen and the way we get oxygen up to the brain is by blood. We know that there are 100,000 miles of blood vessels in your brain. They've wrapped around and the brain is like a walnut, those ripples of a walnut increases the surface area of the brain so we could get more oxygen up to the brain. The brain is divided into two hemispheres, the left and right hemisphere, and we know that the right hemisphere controls the left side of our body and the left hemisphere controls the right side of our body. Each hemisphere contains lobes, which also have functions. So, some parts of the brain will help us with communication. We know the frontal lobe helps with all what we call an executive function which is all the things we do such as adding up, planning what to wear and what to do. It also controls our personality. The brain is very complex and we still don't know enough about it. In fact, we know more about the stars and the planets than we do our own brain.
