What we know about our spine?

The role of our spine is difficult to overestimate. The mainstay of the human body and all its organs is a skeleton (in it about 200 bones), and the mainstay of the skeleton - spine. Attached to the spine all the bodies.
The spine is the main organ through which we can move.
The spine protects from damage due to sudden movements, jumping and running other organs: heart, lungs, liver, brain.
Cope with all these very complicated functions of the spine may be due to its special structure.
Spine person has a slightly curved shape (Figure 1).
This feature of the structure enables a person to move in an upright position and large enough to withstand axial loads. At the same time, the serpentine shape of the spine allows him to be flexible enough to change the position of various parts of the body: to stand, bend, sit, lie, etc. Here are some statistics. The spine consists of rights twenty-four flexibly connected with each other vertebrae, which are held in line with the intervertebral discs and ligaments, which are elastic cartilage pads, as well as the coccyx and sacrum. Coccyx and sacrum are fused vertebrae.
Of these twenty-four vertebrae - seven cervical, twelve thoracic and five lumbar. Total distinguish five spine: thoracic, lumbar, cervical, sacral and coccyx. The spine has bends rights. In the cervical and lumbar spine - bending it forward, and in the sacral and thoracic regions - convex curve ago.
These bends buff in walking and running, it is possible to withstand heavy physical exertion.
The vertebrae in the spine are movable relative to each other. The mobility of the vertebrae provide the intervertebral discs and ligaments and joints.
Inside the spinal canal, which passes through all the vertebrae, the spinal cord is located - automatic station of many body functions. This gentle education adequately hidden inside the spine. Damage to the spinal cord is possible only when he damaged spine.
In the intervertebral holes spinal roots leave the spinal cord, forming the shoulder, cervical, lumbar and sacral plexus.
The structure of the vertebrae to the next - the body, appendages, and the arc (Fig. 2). Dougie vertebra close the holes that form the spinal canal. The combination of these arcs between them is due to joints and ligaments. Ligaments do not give vertebrae repel each other. Inside the intervertebral disc is a special liquid - jelly core. This fluid nourishes the spine, takes away from the circulation are important for its vital elements. At a time when we are asleep, and our spine is resting, jelly core fills the intervertebral discs. Found that night, everyone "grows up" two to three cm, and in the evening he seemed to "shrinks". When our body takes a vertical position, the vertebrae closer together, wheels flattened and the liquid comes out. Intervertebral pads, and their twenty-three to twenty-four, provide mobility and flexibility of our spine, protects bone formation, many blood vessels, nerves from injury.
Resistance disc compression force is simply amazing. When the load on the spine of 100 kg of compressed disk only 1,4 mm. From the state of the intervertebral discs depend on good posture, man's ability to straighten, bend and turn.
Sooner or later, but almost every person with the age there are certain problems with the spine and joints. The website "Treatment of the joints" described methods of treatment of the spine and joints, ways to prevent these diseases through regular exercise, a hardening of the whole organism and other simple techniques.
