BRAIN CANCER
The brain is the organ of the body on which all the reactions
depend
that allow us to act like human beings. It is
a
gelatinous mass of gisáceo color that is prote'ge'e by the bones of the skull and just begins behind the eyes and the nose and extends until the bones of paladar filled up all the craneal cavity.
One extends by means of the
spinal
marrow that crosses the spine until underneath the waist.
Its structure contains
a
trillion of
nervous
cells with million connection points and is the base of our existence, since it controls all the corporal mechanisms. When she lets work, the person dies irreversibly irremediable and.
In the brain are all the senses thanks to which we can see, to smell, to feel, to enjoy the foods and to hear, also are generated the feelings, sensations, emotions, the reasoning, the memory, the
thought
, intelligence and in aim there all the
functions
that distinguish to us of other alive beings, besides to control the breathing, the temperature, the appetite and in general all the processes that regulate our body, since it is the control unit of the human body.
The brain is the most important part of the
Central
Nervous
System
that also is made up of the cerebellum and the
spinal
marrow.
The brain is formed by
a
layer in form of average
sphere
with two halves in form of
nut
of pink gray color that is called córtex or
cerebral
crust, under that is
a
white substance that it is the
spinal
marrow that is formed of
nervous
fibers that form
a
species of wiring that maintains the information. Part is located forming the hard body that connects both parts of the brain and another one extends until the
spinal
marrow returns of her.
The brain is surrounded by three membranes, meninges that when they become inflamed produce the annoying
headache
, since the brain is insensible to the pain because it does not have sensible completions.
The space between the layers mediates and inferior of meninges he is stuffed of
a
yellowish
liquid
called
liquid
cefaloraquídeo, that serves as shock absorber and waters the four
cerebral
cameras, the ventricles and the
spinal
channel.
The brain, is divided in two hemispheres, the right and the left one and in him are located the zones that coordinate the movements, the senses, the tact, the Vista,
the ear
, the
common
sense, the very important reasoning, emotions, learning, speech, communication and other
functions
.
The cerebellum, is located in the later part of the head and it is in
charge
to coordinate the voluntary
muscular
movements and to maintain the
position
, the stability and the balance, among others.
The rachidian bulb, that is the prolongation of the marrow, controls the involuntary processes like: the movement of the eyes and the mouth, the transmission of the sensorial messages like the cold, heat,
fear
, pain, noise, as well as the appetite, the breathing, the conscience, the
function
cardiac
, the corporal temperature, the involuntary
muscular
movements, the estornudos, the cough, the vomits and the swallowing among others.
