The human brain is considered to be the most complex organ we have, and the information which scientists have uncovered up until now is only the tip of the iceberg. Admittedly, science concerning the brain has advanced considerably, but experts all agree that there is still a lot to be learned.
In this short article we be taking a very basic look at brain structure and brain function, and we’ll be doing it in a manner which is easy to understand.
Structure And Function Of The Human Brain
Brain structure and brain function are of course interrelated. Both are dependent on each other, and if something is out of place, the brain loses some or all of its functionality. The first thing we need to acknowledge is the fact that the brain is made up of different sections, with each section playing a unique roll. The four primary brain structures are:
3. Limbic system
4. Brain stem
The cerebrum, also known as the cortex, is the largest brain structure and it is typically responsible for “higher” brain function, such as thought processes and the way in which the body responds to such thoughts.
The cerebellum which is sometimes called the “small brain” consists of two distinct hemispheres, and is responsible for regulating/controlling things like balance; posture; coordination of movements. Scientists also believe that the cerebellum is far older than the cerebrum from an evolutionary point of view.
The Limbic System
The section of the brain known as the limbic system in buried deep within the cerebrum, and it’s often referred to as the “emotional brain” or the “center of emotion”.
The Brain Stem
The brain stem structure is located beneath the limbic system, and is typically responsible for most basic but vital bodily functions such as breathing; blood pressure; heart beat and etc. It is believed to be the oldest part of the brain in evolutionary terms since the brains of ancient reptiles where almost entirely brain stem, without any presence of the other structures they have now.
The Central Nervous System
The central nervous system, in simple terms, is your body’s decision maker and communicator. It controls everything you do. Without it you wouldn’t be able to breathe; blink; walk or even wiggle your toes. The CNS includes your brain; your brain stem; your spine, and then branches out to every part of the body.
This is why the spine is often compared to a freeway where motor vehicles have been replaced by messages traveling to and from your brain at an alarming speed. Interfere with these messages at any point along the route, and seriously problems evolve. This applies no matter which stream of messages gets disrupted – to or from the brain.
