It is the center of the soft , similar to the jelly of the nucleus, surrounded by a ring of fibrous tissue similar to constitute a tire. vertebra and the disc joint is similar to that posed by the knee joint, but not its flexibility, which allows us to various daily activities. The movement range can also be hip with the assistance of a significant increase 【Figure 5】. intervertebral disc is easy to damage and the occurrence of degeneration of the organization. intervertebral disc, bone, ligaments and muscle tissue so that the spine to stabilize 【Figure 6 】. each section behind the foramen vertebral interconnected to form a top-down pipe called the spinal canal, spinal cord or cauda equina through there. the burden of the brain, spinal cord and limbs and trunk of the nerve contact. nerve root from the spinal cord separation , charged with the spinal cord and trunk, visceral nerve contact. nerve root were 31 pairs, in charge of different parts of muscles, skin sensation and reflection.
spinal disease often involving the spinal cord and nerve roots, resulting in muscle weakness, paresthesia, severe incontinence, and even paralysis.
