The human spine is divided into several basic compartments. We recognize the cervical, thoracic, lumbar and cervical spine. Backbone contours are firmly compacted in a single bone (crossbones) and form part of the pelvis. The last of the spine, the coccyx, is connected to the lower end of the crosstalk.
The cervical spine is composed of a total of seven cervical vertebrae, the thoracic of the twelve vertebrae of the thoracic and lumbar spine formed by five lumbar vertebrae. Also, each individual vertebra consists of several important parts that allow it to function properly and thus function the entire spine.
The so-called vertebral body is its main part, which carries most of the weight of an individual. It also provides a place for the storage of a fibrous disc, intervertebral discs.
The intervertebral disc separates every two adjacent vertebrae, serving as a flexible bumper between two hard bone surfaces. It is composed of two parts – a rigid outer layer called the annulus (ring) and the inner layer of a spongy consistency called nucleus (core). If the intervertebral disc is damaged, the soft core can be pushed through the ring in the ring and oppress the adjacent spinal cord roots.
The arched arch encircles the spinal canal in which the spinal cord is housed. There is a spur from the back of the arc. Thorn spurs are just those bones that we feel as we move our fingers down the back. The pairs of transverse protrusions engage with a spindle approximately the right angle, and the back muscles are clamped against them.
Each vert also has four articular surfaces on its surface. Two of them are oriented downward, two of them upwards. They connect the neighboring vertebra to each other to ensure the stability of the spine.
