Human body Facts about the brain

An adult brain weighs up to 3 pounds, usually only about 2% of body weight, but uses nearly 20% of the body's energy!

The brain floats in a fluid called cerebrospinal fluid. This helps protect it from harm, and provides some nutrients to the cells of the brain.

The skull (or cranium), which protects the brain, is made up of 22 different bones joined together.

The brain is made up of three different parts - the cerebrum, the cerebellum, and the brain stem.

The cerebrum, which is the largest part of the brain, is responsible for thoughts, emotions, and senses like touch, taste, smell, and vision. It is what we use to think with.

The cerebellum, which means "little brain, " is what helps us keep our balance, and helps coordinate our body movements.

The brain stem connects the brain to the spinal cord. It is also responsible for all of the things you don't normally think about (like your heart beating, breathing, and digesting food).

The brain is split into two halves; each half controls the OPPOSITE side of the body.

Most nerves in your body connect to the spinal cord, but there are 12 nerves that come from the brain itself. These control some of the most important functions in your body, including vision, smell, facial movement, and heart rate.

The brain contains billions of nerve cells that receive and send signals from the rest of the body.

Every memory you have is safely stored in a special area of the brain called the hippocampus.

The brain works on electricity. The same power that gives you light at night also runs your brain, giving you your thoughts, emotions, and moves your muscles!

Out of all of the oxygen you breathe in, the brain uses nearly 25% of it.

The brain is also responsible for growth, with chemicals called hormones being released from a special gland called the pituitary gland.

When you are born, you have all of the neurons (the cells in the brain) that you'll ever have. They aren't all connected though - that happens when you learn new things, like crawling, walking, or riding a bike.

In order to run your brain, you need to eat good foods that are rich in potassium, calcium and fatty acids such as omega 3.

The last fact, but not least, is that the human brain is around 3 times larger than other animals brains that are our size!
