Human skull consists of two parts, namely

Skull:

Consists of two parts:
Department Qomi CRANIAL be strong and keeps the brain
And my face FASCIAL section is more fragile and speed in facial fracture and be like location of the eyes, nose and mouth
Will encounter difficulty in keeping the joints in the skull, because most of them fixed and fiber type.
There are 3 mobile joints only: two between the bones of the middle ear and joints are small, large and detailed and not fixed a jaw joint TEMPOROMANDIBULAR JOINT.
If we compare the human skull skull monkey or skull dog seen that face is located under the front half of the apical of the skull and there slot name the large hole is the hole that comes out of the spinal cord and be in a vertical and that the cervical spine are arranged so that the human head is Mtoarna and upright without having to exert a lot of effort to remain on this situation (and this is not the case in the monkey and a dog)
Therefore, the muscles that keep the head upright is not big and strong that he does not need to do so because even if working these muscles, the head will remain high (but this is not the case if man was sitting in a boring lesson!).

 

Begins ischemic brain and nerves in the growth of the fetus before the skull, when the start of the skull Baltkon in the fetus, they are of cartilaginous material that surrounds the brain and the cerebral nerves, leaving holes to pass through these nerves. Then become a skull in a number of places instead of cartilage and bone change is scattered in multiple places, and ossification that expands up to a place of communication between the bones.
Atam skull same names Avsam brain that lies beneath.
In some people remain a clear separation and walks to the extent of the nose, named Metopic Suture.

 

-2 - Parietal bone PARIETAL BONE: is bone in the top of the head on each sideAnd where they met named SAGITTAL SUTURE (meeting place of frontal bone with the parietal bone named CORONAL SUTURE)When generating the child be a meeting place for frontal bones and biparietal not Mtazm and Lynn and we call the anterior fontanelle anterior fontanel and we can feel it if we felt. He tenses if the child cried or if Aldgz rose in the head has but Anagafl in the age of 18 months to two years.


Pies Y back a interosseous Alhaddarien -3 - bones in the back of the head (sometimes called the occipital Attm occipital bone) let's call it the back bone of clarity and because this character is sometimes called the LAMBDA.-4 - Bone the TEMPORAL located on each side of the head and translated Arabic: temporal bone, and Torgomnh also: temporary, because the name of the bone is taken from the word TEMPUS and meaning time or time because in that place showing hairs white before other (or as they say in English GREY HAIR .In the German language, the so-called bone b SCHLAFENBEIN any sleep bone!

The surgeon here looking at the surgical center of the brain artery MIDDLE CEREBRAL ARTERY.

 

This second type of bone contains red bone marrow to the blood of it goes through the large veins there are four large veins on each side of the head called DIPLOIC VEINS descending almost vertically to pour in the nearest appropriate vein VENOUS SINUS.

If you look at the beam head up where the reality lies communication between bone and characterizing fractures. As well as you will see, sometimes the middle cerebral artery. As well as veins just mentioned.

If you look at the back of the skull we will see most of the back bone OCCIPITAL and there is the place where human Sindharb if he fell on the back of his head.

 

 

 

Cranial anterior chamber: consists of the frontal bone frontal bone, which is a front turns sharply to the inside roof shall be quarry and call this part:
orbital plate of frontal bone.


Holes in the perforated plate allow the passage of olfactory nerve fibers from the nose to the brain. In fact, if you look good you'll see that this place is in contact with the outside so it's possible that the inflammation goes from the nose to the brain and if it happens to break in that place the spinal fluid around the brain nasal Senqt.
In place of the beginning of the younger wing of the bone brushes are a slot optic canal for the passage of the optic nerve optic nerve and optic artery ophthalmic artery.
Part of the brain that lived in this place is the frontal lobe of the brain THE FRONTAL LOBE.
