Primary Functions Of The Brain

In the article “This is your Brain…” by Roy Wood and Patrick Barker is about understanding the brain and the limitations that the brain has. That the brain controls our body and everything that happens in our body. That there is so much more that the brain does then we ever give it credit for. The brain has three important things the bad attributes, the neocortex and limbic system, and the manages energy.

Connected to the brain stem and is located in the back of the brain is the cerebellum. The cerebellum is responsible for motor coordination and also some learning involving movement. Once someone learns a new motor action that information is held in the cerebellum.

Our brain is separated into several regions that undergo different kind of information. Then there are regions that process information such as visual, verbal communication, auditory, emotions, etc. These different regions communicate with each other and each one of them has its own processes it has to complete first. For example one looks at a piece of art and express their emotions with language, thus working the verbal function part of the brain.

The Thalamus: The Thalamus is located in the centre of the brain, it controls attention span, helps the body to sense pain and keeps track of the sensations that the body can feel.

The brain has many parts such as the frontal lobe and the cerebellum, which both play major roles in the Human Brain.My first topic is the parts of the brain and all what it controls,in this topic we will cover the frontal and temporal lobes.We will be covering the cerebellum and its parts inside too.We will talk about how the brain sends nerves from the frontal lobe to your eyes to cry or how your temporal lobes send nerves to your nose to smell.

A lot of people don't realize how crucial the brain is in every task we do, even down to just the slightest movement. The nervous system is responsible for almost all things in your body, “This system is responsible for sending, receiving, and interpreting information from all parts of the body”(Bailey, Regina). This system allows for things such as major organ function and muscle movement. It can go from regulating your body temperature to just moving your fingers, even the movement of your eyes as you read this!

Hormonal disturbances-An each need to avoid any that can disrupt hormonal in the body. Studies shows that, brain will always keep up hormonal balance when nervous system responds properly to hypothalamus(part of brain) that connects with hormones releasing system(endocrine system).This enables hypothalamus to properly regulate basic needs such as thirst, hunger, sleep and sex in addition to stress and emotional responses. All this enables brain to stay healthy.

“I not only use the brains that I have, but all that I can borrow.”, Woodrow Wilson had once said. Although we cannot borrow other people’s brains, our own brains can do many things. The brain is the very thing that helps people survive. Do you ever recall telling your heart to keep beating? I don’t remember doing that before. It is your brain that does that for you. “Your brain is the boss of you.” (Your Brain and Nervous System). How does the brain work?

As said in the first paragraph, the brain is a very complex organ of the body. You can think of any animal- mammals, birds, reptiles, fish- and they all have a brain. It is not the largest organ in the body, but does give us the ability to speak, eat, think and problem solve. The brain executes a various number of tasks, which include controlling the body temperature, acknowledging the world around you from your five senses, handling your physical movement like walking, talking or standing, and allows you to dream, reason and experience emotions. Your brain is attached to your spinal cord, which has your peripheral nerves and is known as your central nervous system. This is ultimately referred to as your “control system” because it regulates all the conscious and

Because the brain is so paramount, it has many crucial responsibilities; It is accountable for all of major functions, including what people are able detect, regulations of vital functions, and how the body interacts with the world in which it inhabits. As far as detection goes, the brain is answerable to how an individual notices odors, light, sound, and pain. (Brain) In like manner, The mind of a person regulates integral functions: mankind is capable of phenomenons such as strategizing and reasoning, the ability to speak and communicate with one another, and the faculty to obtain memory, and to focus on an event or object. Instinctual things, such as suxual inclination and sleeping and eating regulations, are also dependant on stimulus from the human brain.

The first brain division is the Cerebrum, which carries the most unique human qualities (problem solving, language, planning, reasoning, etc). It is the largest division of the brain, encompassing 40% of the brains weight. Consisting of the mirror hemispheres, the right and left hemisphere, the cerebrum is section into six lobes (frontal lobe, occipital lobe, two temporal lobes & two parietal lobes) that specialize in certain functions. The next brain division is the brainstem which is located directly at the top of the spinal cord. The brainstem serves as a conduit between the spinal cord and the brain. The brainstem is a transmitter of sensory information to the brain and away from the brain it is a key transmitter of motor information.

After reading both of the articles on the human brain, I have learned a lot of things that I never knew of. But the three facts  that I learned about the brain that I didn’t know before was on the national geographic site, the article brain stated that the "brain's nerve cells are known as neutrons, which make up the organ's so-called "gray matter" (National Geographic, n.d.).  That the cerebellum which is the second largest part of the brain is "responsible for coordinating muscle movement and controlling our balance, and the cerebellum transmits information to the spinal cord and other parts of the brain" (National Geographic, n.d.). Also on The Human Brain article the limbic system "regulates body temperature, blood pressure, blood sugar level, and other housekeeping activities. Also, the limbic system exists only in mammals"(The human brain, 2001).

Each hemisphere is dominant for different traits. The right hemisphere is responsible for the creative thinking in your brain. (Creativity, imagination, music, etc.). Also responsible for our insight and left hand coordination skills. The left hemisphere is responsible for the logical style of thinking in your brain.

The brain is the control center of the body. It controls the conscious and the unconscious body processes.

The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning, planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain more convenient, as this increases the brain's surface area, giving it more room for neurons. The cerebrum is divided into two hemispheres- the left hemisphere, and the right hemisphere. The right hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum, since it also has two hemispheres and a highly folded surface. This part of the brain is linked with movement and balance. The cerebellum is assumed to be older than the cerebrum "evolutionarily" (Brain Structures and Their Functions). The brain stem controls basic life functions such as blood pressure, breathing, and heartbeat. Scientists say that the brain stem is the simplest part of the brain (Brain Structures and Their Functions).
