The role of our spine is difficult to overestimate. The mainstay of the human body and all its organs is a skeleton (in which about 200 bones), and the support of the skeleton – spine. Attached to the spine all the organs. The spine is the main body, with through which we can move. The spine protects from damage during 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. Human spine is a little bent out of shape.

This structural feature gives a person the ability to move in a vertical position and can withstand fairly large axial load. At the same time, the serpentine shape of the spine allows it to be flexible enough to change the status of various parts of the body: to stand, bend, sit, lie, etc. We give some statistics. Spine person consists of twenty-four flexibly connected to each other vertebrae, which are held in line with the intervertebral discs and ligaments, cartilage is an elastic strip, and the coccyx and sacrum. Coccyx and sacrum are fused vertebrae. Of these twenty-four vertebrae – seven cervical, twelve thoracic and five lumbar. Total distinguishes five parts of the spine: thoracic, lumbar, cervical, and sacral coccygeal.

Human spine has curves. In the cervical and lumbar – is bending forward, and in the sacral and thoracic – bend convexly ago. With these curves buff when walking and running, there is ability to withstand heavy physical exertion. Vertebrae in the spine 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 many body functions. This gentle education adequately hidden inside the spine. Spinal cord injury may only if damaged spine itself. In the intervertebral foramen spinal roots leave the spinal cord, forming a shoulder, neck, lumbar and sacral plexus. The structure of the vertebra following – the body processes and the arc. Arc vertebra close the holes that form the spinal canal. The connection between these arcs are going through the joints and ligaments. Ligaments do not give vertebrae repel each other. Inside intervertebral disc is a special liquid – gelatinous core. This fluid nourishes the spine, takes from the blood are important for its vital elements. At a time when we sleep and our spine is resting, gelatinous nucleus fills the intervertebral discs. Established that night every man "grows" on two or three inches and in the evening he seemed to "shrinks". When our body takes a vertical position, the vertebrae closer together, wheels flattened and liquid coming out. Intervertebral pads, and three and twenty to twenty-four, provide mobility and flexibility of our spine, prevent bone formation, many blood vessels, nerve endings from injuries. Resistance to compression of the disc force is simply amazing. When the load on the spine of 100 kg disc shrinks only 1.4 mm. The state of the intervertebral discs depend on good posture, a person's ability unbend, tilted and rotated. Sooner or later, but almost every person with the age there are certain problems with the spine and joints. The website "The treatment of the joints" described methods of treatment of spine and joints, ways to prevent these diseases through regular physical activity, hardening of the body and other simple techniques.
