Explanation of the cervical spine

 

 

Cervical spine:Vertebral body is smaller than the small thoracic vertebral body (because he carries less weight than weight carried by paragraph pectoris). And be Huktha smaller and cracked. But more than what is observed is that the extrusion browser where the height of the front and rear anterior and posterior tubercles and hole: foramen transversarium. It's easy to remember this if I thought that the whole paragraphs, as if ready to link thoracic ribs such as ribs. In the cervical spine and lumbar and sacral the "ribs" These integrated in the same paragraph. In the lumbar and sacral rib imagine integrated in the same paragraph and can not be distinguished. But in the cervical spine is a different matter. This is important to understand that in some people there is a rib "neck" is linked to paragraph the seventh may cause cervical blockage of the arteries, veins and nerves and all symptoms resulting from it.

The first cervical vertebrae called Atlas atlas: the first paragraph in the spine and form a loop. It links skull Bpfih spine. And characterized by several things:Do not have the vertebral body. That's because her body has docked with the next paragraph (during fetal life).
Atlas surface over its oval form or college because he يتمفصل with Ntoin skull occipital condyles. But the lower surface is rounded. Pay attention also to the hole on its top surface, which passes the vertebral artery. As Shaw argema it is very small, a small rise. To it's وكانت big it would have hampered the movement of the skull private back (in other words, when you look at the sky), while the Alentuan Almstardhan Taiwilan It works as a lever of the muscles, which manages the head. (Praise God ..)

Spin and settle paragraph Atlas paragraph axis.The fork is great to relate muscle.



Form Atlas and Axis distinctive because they head Asindan and allow him to spin and movement on the spine.
The seventh cervical vertebrae: is also a distinct paragraph is to be a compromise between the cervical spine and the thoracic spine (in place and in shape). She does not have high front or back extrusion browser but its browser hole.
Lumbar spine:
Is the largest paragraphs in the body. And growing up whenever we went down from high to vertebrae below.Huktha great and stand out to the back and do not cover each other as happens in the thoracic spine. So easy inserting a needle between them, as in the case of lumber puncture. Alentaan Almstardhan also strong and fifth lumbar vertebrae easy to know its location.

Sacral paragraphs:Are five vertebrae fused together to be one bone. Continue from the bottom with the coccyx. Since it four sacral vertebrae Fbanha four spaces. When the deficit aspects pelvic bone.
Joints between the vertebrae: inververtebral joints:
Between vertebral bodies (where place carry less body) there cartilaginous joints of the kind. Each body paragraph covered with a layer of cartilage gel between the opposing classes there is a thick disk Levy disc. Intervertebral disc consists of1 - external part is a ring of fibrous annulus fibrosus fiber span to give more power2 - be thinner than the outer part and named nucleus pulposus

landmarks:

Base of Nose and the Hard palate corresponds to C1.
Teeth (when mouth remains closed) correspond to C2.
Mandible and Hyoid bone correspond to C3.
The thyroid cartilage is from C4 to C5. [1]
The cricoid cartilage is from C6 to C7. [1]
