Anatomy of the brain

The anatomy of the brain is very interesting because scientists say that man has four brains. The human brain has it's specific functions and are divided into several sections. In this hub I will explain the different sections of the brain and their functions. But the must interesting fact is that the fourth brain is not located where you think it is.

We often refer to our cerebrum as the brain, thinking that it is where all our bodies' functions are monitored. We believe that without the cerebrum man cannot survive. I will attempt to explain to you the anatomy of the brain and that there are several primary monitoring systems in the body that perform very vital functions for different organs.

Man has four brains that are located at different sections of the body. These brains as they are often called are really a network of nerve fibers that consist of grey and white brain matter. They are called brains because without them the body's functions will be retarded. Man is unable to function without these "brains".

Brain 1 - The Cerebrum

The cerebrum is the front of the main brain situated in the head, scull or cranium. The cerebrum consists of two equivalent parts that are made of white matter surrounded by a grey substance.

The front portions of this brain are responsible for voluntary activities and intelligent functions of the body. For instance these portions of the cerebrum are responsible for the movement of the eyes, mouth, hand and feet.

If this part of the brain does not function well or is injured we may lose our motor skills.

Brain 2 - The Cerebellum

Simply put the cerebellum is located behind the cerebrum and is made up of white matter with grey substance on it's surface. The white part of the cerebellum looks like a little tree with trunk and branches and leaves. The brain is responsible for power force functions and sexual activities. Orgasms are also controlled by this portion of the brain.

The section circled in red on the diagram is the cerebellum. As you can see it is located at the back of the head.

With out the proper functioning of this brain the ability to function normally sexually will be severely affected. Injury to this part of the brain may make us lose interest in sex and or unable to reach a sexual climax.

Brain 3 - The Medulla Oblongata

The Medulla Oblongata is located at the upper end of the spinal chord. In this brain is the great gangionic centers which control respiration, vomiting, degutition etc. In hanging, it is said that the cause of death is the pressure that is placed on the Medulla Oblongata. The Cranial nerves are situated in the interior of the Medulla, under the surface of the cranium and emerging from the cranial cavities through openings in the base of the skull. These nerves are distributed to the head, neck, to some thoracic and abdominal organs, and the organs that perform special sensory functions.

Brain 4 - The Solar or Celiac Plexus

There is an entire hub dedicated to the solar plexus. Read it here.....................

      Hi Torrs13. I like psychology as well and am always investigating how the mind works. I think the brain is so diverse that man will never fully understand its functions.

      The brain is so interesting to me. I'm getting my master's degree in psychology so I am constantly researching the brain and how it functions, as well as why people think and behave the way they do. I hope that one day there is enough research present to be able to identify why various disorders occur and how they may be fixed or altered so that people don't have to suffer from being taunted by their own minds.

      Nice, I just learned something.

      .... the thing about hanging and the medulla oblongata. Thanks!

      LOL when I saw the headline my first thought was "oh, no wonder men are complicated, they have four brains!" I didn't expect a biology lesson. Nice one!

      some of my motor neurons were damaged when I was born. as a result, I was born with slight CP. The most severe damage is in my right hand where I have little dexterity except in the thumb.
