The Brain, the most complex organ in your body, is made of soft tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation and intellectual and nervous activity. The average brain weighs about 3.3 pounds and makes up about 2% of a human’s body weight. In this article, you’ll learn everything you need to know about your brain from inside to out. Many like to call it the command center for the human nervous system, as it is one of the main reason as to why your body functions that way it does.
Here are a few more added facts for you to understand the brain and the way it works in your body. It contains about 86 billion nerve cells (neurons) or “The Gray Matter”. It also contains billions of nerve fibers (axon and dendrites) or “The White Matter”. These neurons are connected by trillions of connections or synapses. The brain is comprised of of specialized areas that work together to function itself, as well as divided into several lobes that specialize in different areas of your learning! Keep reading on to find out what your brain is comprised of and how it actually works!
What Is In The Brain?
As already mentioned, the brain is one of the largest and most complex organs in the human body. It is made up of more than 100 billion nerves that communicate in trillions of connections called synapses. So what is the brain comprised of? It is made up of many specialized area that work together. These are:
- The cortex. This is the outermost layer of brain cells. Thinking and voluntary movements begin in the cortex.
- The brain stem. This lies between the spinal cord and the rest of the brain. Basic functions like breathing and sleep are controlled here.
- The basal ganglia is a cluster of structures in the center of the brain. It works to coordinate messages between multiple other brain areas.
- The cerebellum. This is at the base of your neck and the back of the brain. It is responsible for coordination and balance.
The brain is also divided into several lobes:
- The frontal lobes. This is responsible for problem solving and judgement and motor function.
- The parietal lobes. These manage sensation, handwriting, and body position.
- The temporal lobes. These are involved with memory and hearing.
- The occipital lobes. They contain the brain’s visual processing system.
Our brains are also surrounded by a layer of tissue called meninges. The skull helps protect the brain from injury.
What Are Some Facts About The Brain?
- Your brain keeps developing until your late 40’s.
- New brain connections are created every time you form a memory.
- You brain uses 20% of the total oxygen and blood in your brain.
- When awake, the human brain produces enough electricity to power a small light bulb.
- It’s scientifically proven that even a small does of power changes how a person’s brain operates and diminished empathy.
- There are taste receptors in the stomach, intestines, pancreas, lungs, anus, testicles and the brain.
- 60% of your brain is made up of fat.
- The smell of chocolate increase theta brain waves, which triggers relaxation.
- Deleting unnecessary information helps the nervous system retain its plasticity.
- Long term mobile phone use significantly increase the risk of brain tumors.
- Sleep deprivation affects the brain in multiple ways that can impair judgement and slow reaction.
