Deep muscles

The short, deep-lying, back extensors have the task of supporting the spine and spinal joints. Primarily, they adjust the facet joints in an optimal position with regard to the intervertebral discs. When the musculature of the spine is strengthened, the nerves of the spine are given more room.

The nerves of the spine branch out from the spinal cord, which is inside the backbone, and from there connect to their target organs and muscles.

The more stable the core muscles, the greater the distance between two vertebrae and the more room for the nerves. Nerves that exit from the spinal cord control the functions of all organs and all muscles. Numbness in the fingers, tinnitus in the ear, a stinging feeling in the chest, occipital headaches, tennis elbow, sciatica and many other disorders can be traced back to a compressed nerve.
