Back & Spine
Why is the back and spine
unique in humans
With its double S-shaped spine, strong muscles and stable ligaments, the back performs an important function without which our human life would not be possible: the back enables us to walk upright. It therefore makes us unique among all living creatures!
What is the purpose of intervertebral discs?
An intervertebral disc is located between two vertebral bodies. It consists of a fibrous ring, which is firmly connected to the vertebral body above and below it, and a gelatinous, almost liquid core.
The intervertebral discs ensure that pressure is distributed fairly evenly when the spine is subjected to uneven loads – for example, during flexion – and thus protect the vertebral bodies from uneven wear and tear.
Intervertebral discs are not supplied with blood. They are nourished by the surrounding tissue and surrounding blood vessels.
Intervertebral discs can regenerate to a certain extent, which can also be observed on a daily basis: in the morning, the discs are higher and filled with more fluid; in the evening, they have lost water content due to walking upright, among other things.
