Our Amazing Human Body: Brain

I think the most amazing organ in our body is the brain, is so wonderful that is the organ in charge most of the human body functions.

Well, the brain is located in the head protected by the cranium. Besides, of all the weight of our body, the brain only represents between 0.8% and 2% (approximately 1300 to 1600 grams).

The functions of the brain are many, I might write all the day about the brain, but that is not the idea, so, I will summarize.

The brain processes sensory information, controls and coordinates the movement, behavior, feelings and can prioritize homeostatic body functions such as heart rate, blood pressure, fluid balance and body temperature. However, the responsible for carrying automatic process is the medulla oblongata.

What illnesses can alter its normal functioning? Inflammation in the brain can lead to problems such as loss of vision, weakness and paralysis. The loss of brain cells that occurs when one suffers a stroke, can affect the ability to think clearly. Brain tumors can also press some nerves and affect brain function. Some brain diseases are genetic; in others, such as Alzheimer's disease, the cause is unknown.

A balanced diet is essential to promote brain health. We must also avoid stress, proper rest and encourage neural connections learning something new every day.

Important information: 

• Only about 5 minutes without enough oxygen for brain, damage occurs. 
• There are no pain receptors in the brain itself, is, this organ can not feel pain.
