The central nervous system consists of the brain and the marrow and the peripheral is formed by 31 pairs of spinal nerves that come from the marrow and the 12 pairs of cranial nerves that give motor innervation of movement as well as sensory throughout the body.
In the first place it gives us information about the sensitivity of everything that happens in our own body, bringing thousands of data so that we become aware of the placement of each segment of the same in space and also informs us, for example, about the pain we might be suffering.
On the other hand it communicates us with the outside world mainly by the sense of sight, but also with the hearing, smell, touch, etc.
Motor innervation is responsible for bringing the motor information from the brain to all parts of the body in order to move them.
These two systems work together so that the motor system works driven and supplemented by the sensitive system.
All this network of nerves stretches through the body in order to perform the abovementioned work. In some cases and for different reasons these nerves may be compressed in a manner such as to cause undue stresses. An accident, poor posture repeated at work or any other reason can cause such compression and injure the nerve.
Neurodynamia is a way for restoring the physiological movement of the nerves.
