How does the brain work?
The human brain is one of the most powerful parts of the body because it is the heart where all human functions are processed and coordinated in a manner to bring harmony in the body and to enable a person do what is expected at a given time. Moreover, the brain plays a vital role in enabling human beings to speak and understand each other, to identify problems and come up with workable solutions and to think, remember and learn.
Other body functions also largely depend on the brain for their functioning such as the regulation of body temperature, the normal flow of the blood as well as breathing.
It is also responsible for the co-ordination and working of our 5 senses i.e. seeing, touching, hearing, smelling, and tasting as well as enabling us to have a sixth sense which can help us detect abnormality easily.
Human functions such as standing, sleeping, walking, eating, digesting, working etc., also depend on the reasoning which emanates from the brain.
This means that the brain has an interconnected network all over the body so that it can be at a position to send commands, process information for different parts of the body and regulate all these activities in a coordinated and harmonious manner.
The network is made up of the brain and nerves which are spread throughout the body and are carried down from the head through the spinal cord. This network makes up what is referred to as the central nervous system.
To enable distinct sending, processing and regulation of different body functions, the brain has billions of nerve cells called neurons which are electrochemical in nature hence their ability to send signals to from the brain to the respective body part. They work at a very high speed hence signals and information are processed very fast.
There are different types of neurons which are usually classified according to their functions and they include;
These are neurons which are responsible for carrying out signals from the various parts of the body to the brain so that the signal can be processed. E.g. when you touch something which is hot, the sensory neurons will send a message to the body and that’s when you feel pain. The same case happens when you smell something.
These are responsible for carrying out signals and information from the central nervous system to the respective body parts. Therefore they are responsible for the functioning of any part of the body.
These are responsible for connecting other neurons in the central nervous system.
