Skull bones

Head Bones

Head, based on the upper end of the spine, back in front of the large, oval shaped part of the skeleton. All the bones in the lower jaw bones that make up the informal He is united with each other, not play, this merger is with eklemleşme sinartros group.
The head, divided into two parts:

1) head; the bone cavity tümbeyin containing 8,
2) Face; are 14 bones, have occurred.

(In this section, in between the bones of the head, location, number and shapes of different bones as soon as the little worm.)

Skull bones, skull bone

There are 8 bones in the head, 4 ü ortaca is unique, and the two sides even. The only ones in the middle, and back to front:

1) occipital bone (occipital)
2) wedge, or the basic bone (sphenoid)
3) Kalbursu bone (ethmoid)
4) get the bone (frontal)

Sides, and double ones:

1) Wall or peripheral bone (parietal)
2) Temporal bone (temporal)
Occipital bone

The back of your head, the lower and middle part, a single and symmetrical bone. Between the temporal and parietal bones in the Atlantic on the bone, sphenoid bone behind. One of the other is the vertical part of this bone there are two horizontal, vertical section of the form of a sphere is part of the sides is reminiscent of an irregular rectangle, the horizontal section in the middle of a large oval shaped, the tip shows a hole in the back. Through this hole, called a large hole in occipital, bulb, vertebral arteries, and n. accessorus'un through the roots. 35mm front to back width of 30 mm. The diameter of this hole, channel, combines the head space of the spine.

To read this bone, occipital formations around the big hole will be reviewed:

1) front, pars basialis
2) Lateral, pars lateralis
3) At the rear, pars squamalis

1) part of the base, this piece is in the form of rectangular thick and wider than the back forward. Lower on the center line on the 1 / 3 part of the back with a 2 / 3 at the junction of the front piece has a protrusion called the pharyngeal tubercle.

This is a little bit in front of the tubercle, from front to back length, which is pitting the foveal navicularis name. Middle of the line on both sides of some of the muscles of the neck seal off the bone ibikcikleri konkavlığı curvatures are looking forward.
The lower side of the base part of the off-side of the head.

Intracranial part of the upper face of the base (endocranialj face. This indicates that face-to-back and down a groove that is deeper than the front and rear, located in the bulb and the pons, the clivus is called the gutter.

Temporal part of the side edges of the pyramid makes with the base of neighborhood, the front edge, are joined with the sphenoid body. The front edge of the rear edge of the hole in the middle of the occipital side components, such as extending the sides.

2) side-track; occiput with a large hole along the convex side of the track and elliptical kafad i e s, a large ridge axis there are two facing forward and inward so-called occipital The occipital joint make these projections atlasla.

In contrast to the situation on the surface of this atlas lokmalara warning içyandan dışyana convex from front to back, and a narrowing of the show in the middle of the condyles.

Intracranial face, this face, leading to a bulge of the tubercle jugulare name, his or her back through the 9 th, 10 th, and 11 th of nerves passes in a groove, Nervi hypoglossi'nin inside the mouth under the canal, the lower back and outer sides of the sulcus sygmoides'in is part of.

The edges of the side parts, the inner edge of the hole on the sides of occipital borders, the inner edge than outer edge is a long and intricate process of condyles at the level of dışyan jugularis name of the ridge is divided into two parts. The rear section is pürtükîü I. combines the temporal mastoid process. Taking the front part of the name of the foramen jugularis incusura. jugulare'nin içyan shows to make up a notch.

Foramen jugulare, the temporal incisura jugularis piramis piece name is a hole in the notch between occipital'in inc'sura jugularis. This is a rather large hole in the bone of both the process of insizur intrajugularis many times over the name of the two bones are divided into two parts, with dikenciği. Vena jugularis interna the rear parts of the front parts 9, 10, 11 th through the nerves.

3) Sedefsi track, this track wide, flat and lozenge form, both sides, has four sides and four angles.

Kafadışı face, this percentage over the center line and center, there is a ledge above rough; occipital area of the outer protrusion name below and forward this projection, the occipital crest is seen as a large hole.

External occipital and occipital external ibiğinin çıkıntısından cross from side to side as the middle two lines are seen. Line of the upper neck to the outer side of these advances mastoide; neck after going to the bottom line on the sides for a while and transverse process of winding down and the forward ends jugularis.
These two are not equal gençlikçe from neck line. The lines between the adhesion to the surface of neck muscles.

Intracranial face, this face again in the middle on the middle line shows a bulge. External occipital ridge is wider than the fluffy and the projection:
1) the two groove sideways, 2) the other a groove vertically upwards, 3) down to begin a bone comb.

Side-grooves, sulcus transversus dışyana içyandan name is located, and a little above the edges of the advancing down the track sedefsi transverse direction.

Is the vertical groove down the name of advancing the vertical crest, internal occipital crest occipital crest, which is called before the two branches after leaving a large hole in the side edges of this hole will be lost.
The groove width and vertical comb, the face of intracranial skuama'nın separates four pit. This pits the top two of the fossa occipitalis cerebralis; bottom holes are also called the fossa occipitalis cerebellaris.
Edges; Skuamanın upper side edges of the parietal bones combined with the lower side edges of the lambdoid suture combined with the temporal mastoid process.

Angles; side angles of temporal bone mastoid angle of the ledge they fit together, this point is asterion name.

The merger of the two parietal angle encounters occurred in the upper corner. Lower angle, occiput large hole in the middle of the back edge of the side pieces combined disappeared.
