Human Brain: The Most Vital Organ
There is a philosophical line that “Sky is the Limit” and it suits quite aptly with the human brain which, has unfathomable potentials and is basically the most enigmatic, most fascinating and most powerful organ on this planet. It efficiently channelizes the working of all the other organs. So, if we move our hand or kick a ball; all the commands to do so come from brain. Functioning of heart, liver, lungs or any internal/external organ is dictated by this amazingly potent organ. If the leg of somebody is paralyzed then problem is not in his leg, problem arises from the brain. There are multiple researches has been done and now we know a lot about the brain and it’s potential. We are also quite aware of the fact that potential of human brain is still very much unutilized. Mostly we use about 4-10 percent of the potential of our brain and it is also quite evident that even with that minuscule percentage, lots of miracles has been done.
Human brain generates electricity and it can easily lighten up a bulb of 25 watts. Different brain cells run on the electricity and our thoughts travel through these brain cells on that electric current. Brain has about 110 million brain cells, also known as neurons and that quite efficiently provides us the ability of information processing and computation. In this article, I am going to tell you about some physical aspects of our brain as, it is the brain which makes our life meaningful or worthless, exhilarating or dumb and we should know about the different intrigue details of this engrossing and powerful organ.
Different Physical Aspects of Human Brain
The weight of adult human brain is 1.4 kg and it is only 2 percent of the body. Our brain which is safely secured in our head should never be confused with the mind. Basically, if the human brain is the hardware then mind is software. So, while mind is totally functional, brain is completely physical. Brain can be divided into three parts:
- The Brain Stem
- The Cerebellum
- The Cerebrum
1. The Brain Stem: When the formation of the brain starts in the womb then brain stem is the first part to be formed. It has its existence just atop our spinal column and there it incorporates three nerve centers, known as Mid Brain, Pons & Medulla Oblongata.
Different nerve centers present in the mid brain is made to control the movement of eyes while Pons efficiently interconnects to hemispheres of the cerebrum. The third nerve i.e. medulla oblongata quite effectively regulates the blood flow, heartbeat, and breathing of our body. So, here it is quite clear that the functioning of brain stem is the base of the survival mechanism of our body.
2. The Cerebellum: It efficiently manages the movement of our body and it has its existence just behind the brain stem. Cerebellum stores the memory of movement which is known as muscle memory or kinesthetic memory and mostly cerebellum of the good athletes are well developed.
3. The Cerebrum: In the process of evolution, cerebrum is basically the final stage of our brain development. This is responsible for all our feelings and thinking. Cerebrum is also divided into four different lobes, which are mentioned below:
- The frontal Lobe which efficiently deals with all the abstract problem solving.
- The Parietal Lobe which helps in the processing of the information from the different senses.
- The Occipital Lobe which perfectly governs visions.
- The Temporal Lobe which controls language, hearing and memory.
Cerebrum also includes Limbic System & Neocortex. Both of these two work in tandem with each other. Limbic system is basically the feeling brain while on the other hand neocortex is the thinking brain. Limbic system creates the interaction in between thoughts and emotion and it also interfaces brain with endocrine system. Due to the stimulation of the limbic system or physical health, successful channelization of emotional and intellectual aspects of the life occurs appropriately. Primary parts of the Limbic System are divided as follows:
- Hippocampus: It is used for storing all the dry and unemotional facts of short term memories and it also efficiently ships most of the long term memories into the neocortex for their storage.
- Amygdala: It stores all the emotional memories as whenever any sorts of emotional impact occurs in any thought then that naturally gets shifted into long term memory. So, for the long term memories emotions are extremely crucial.
- Hypothalamus: The primary function of hypothalamus is basically to tell the body about how to respond in different circumstances. It is used for controlling hunger, sexual functions and temperature and in any situation of crisis, it sends out orders for the more adrenaline flow.
- Thalamus: This works as the relay station by picking up all the incoming sensory messages (except smelling) and relaying them to the required processing centers in the brain.
- Pituitary: It is used for giving orders to other glands about their functions and it is basically the master endocrine gland. Pituitary is also considered as the third eye which is involved in the intuition. It helps body in producing different hormones as per the requirements of the situations by receiving the messages from the hypothalamus.
