The brain is the most complex organ in the body. The brain is made up of a complex network of billions of nerve cells called neurons, as well as other kinds of cells, all protected by the bones of the skull. It gives rise to our basic instincts, and complex emotions and feelings.
We can store memories, learn new skills and react to stimuli, all through the function of the brain.
Let’s look at some fun facts about the brain:
- One of the most interesting facts about the brain, is that it is our fattiest organ, being composed of 60% fat cells. This is not a well-known fact about our brains.
- Additionally, the human brain uses a large amount of energy to carry out its executive functions. It only represents about 2 percent of our total body weight; however, it uses 25 percent of the body’s glucose, and requires 20 percent of the body’s oxygen levels. The brain is a powerhouse that requires huge resources to run properly.
- Our brains cannot feel any pain! Having no pain receptors, the brain would not feel a slice, punch or shock as it cannot interpret pain. The absence of these receptors means that brain surgeries can be executed with no pain medicine for the brain.
We can therefore see that the brain is an incredible organ, with many secret talents that we may not have known.
The human brain is mysterious, complex and deserving of some additional thought. Weighing only three pounds, this organ gives rise to our feats as human beings.
