Dyskopatia szyjna jest jedną z pierwszych oznak degeneracji krążków międzykręgowych (zmian zwyrodnieniowych w kręgosłupie). Najczęściej obejmuje segmenty C5, C6 czy C7. Przyczyny dyskopatii to m.in.: brak ruchu, stres, przeciążenia oraz urazy odcinka szyjnego.
The C3, C4, and C5 vertebrae form the midsection of the cervical spine, near the base of the neck. A cervical vertebrae injury is the most severe of all spinal cord injuries because the higher up in the spine an injury occurs, the more damage that is caused to the central nervous system.
18 sty 2022 · Cervical nerves C1, C2 and C3 control your forward, backward and side head and neck movements. The C2 nerve provides sensation to the upper area of your head; C3 gives sensation to the side of your face and back of your head.
When pain, numbness or paresthesia -- tingling or a pins-and-needles sensation -- appears over a specific dermatome, it could signify damage to the corresponding cervical nerve. The C4 nerve receives sensory input from the dermatome that covers the shoulder, collarbone and shoulder blade.
In between C5-C6, the C6 spinal nerve exits the spinal cord through a small bony opening on the left and right sides of the spinal canal called the intervertebral foramen. This C6 nerve has a sensory root and a motor root. The C6 dermatome is an area of skin that receives sensations through the C6 nerve.
Cervical levels C 1 –C 4 are the main contributors to the group of nerves called the cervical plexus; in addition, small branches of the plexus link C 1 and C 2 with the vagus nerve, C 1 and C 2 with the hypoglossal nerve, and C 2 –C 4 with the accessory nerve.
