· Brain is captain in the human body.
· The Brain has 3 main parts, the cerebrum, cerebellum and the brainstem.
· The frontal lobe of your brain controls your memory.
· The human Brain is smarter than a gold fish’s (gold fish are not that smart because every 7 seconds later they forget.)
· The main part of the Brain is the cerebrum.
· The Brain controls all systems of the body.
· You can lose parts of the Brain and not die.
· The human brain makes up 2% of the body’s total weight, but uses up 20% of the body’s oxygen supply.
· The Brain weighs 3.5 pounds.
· The left hemisphere of the Brain controls the right side of the body and vise-versa.
The cerebellum controls fine movement coordination. It also controls balance and stability and muscle tone. The cerebellum is located just above your brain stem. It controls posture, walking, running and coordination.
The Fore brain contains the cerebral cortex, temporal lobe, occipital lobe, and parietal lobe. The Nervous system is to relay electrical
signals through the body. Major structures of the brain: Cerebrum, Thalamus, Hypothalamus, Pituitary gland, Brain stem, Medulla oblongata, Pons and the Cerebellum. The left cerebral hemisphere controls spoken language, math skills, scientific skills and writing skills. The right cerebral hemisphere controls imagination, artistic skills, 3-D forms and musical skills.
If anyone tells you your memory is hopeless, don’t believe him or her! The human brain can remember thousands of words, details of faces and complex tasks. How? There are billions of tiny neurons in one human brain each one can connect with thousands of others. When you remember something like how to ride a bike. Your brain probably does it by making a new pathway for nerve connections; this is called a “memory trace”. You forget things as the connections break down from lack of use.
Scientists measure bursts of electricity from every single little brain cell using an electroencephalograph, or an EEG. Scientists attach electrodes to the head to record the brains electrical activity and display on a printed out graph or a wavy monitor. EEGs show that when you are awake your brain is still working, with a lot of cells are blasting of at once that there is no real pattern. But when you start to feel sleepy, brain cells fire off in a more organized way, and normal pulses of electrical activity, these are called alpha waves, moves across your brain every tenth of a second or something like that. Slower pulses called theta waves soon start to appear. When you doze off, your breathing and brain waves become more regular. This is called stage 1 sleeping. In a few minutes you enter stage 2, and your waves become stronger. Over the next 90 minutes or so you fall gradually into a deeper sleep. When you enter stage 3 and 4, your waves slowly but surely become stronger and stronger until your brain starts to throb once or twice a second, with the cortex ticking over quietly. Suddenly, your body starts to move, your breathing is not at its regular rhythm and your brain starts to buzz with action and nerve cells blastoff all the time your still sleeping. What’s more. Your eyes begin to move side to side very very fast under their lids. This is called rapid eye movement or REM. Scientists think that when you are having REM, you are dreaming. Throughout the night, different periods of REM sleep only lasting about 30 minutes or so seem to change with periods of deeper and deeper sleep. These periods of non-REM sleep get gradually shallower until you finally wake up.
There is another system inside your brain. It is called the limbic system
and it controls your sensations. The limbic system is positioned right in the
core of the brain. The limbic system is the memories “arrival meal”.
It also controls emotions and detects smell.
The brain is a very complex organ. We could go on and on with information but we want to get one thing into your head. The brain is the boss in the human body. Remember this “without the brain you could not do a thing”. There is some liquid is inside your brain and that gives your brain nutrition. The brain uses oxygen too. If the brain didn’t use oxygen, the brain wouldn’t work, Oxygen couldn’t comes to the head. So first oxygen comes to the nose and then goes to the lungs and then flows into the blood and then goes to the brain.
