Third, the outer shield affects common mode impedance of the cable outside much more than it actually affects common mode ingress.

Other causes of syringomyelia include an injury to the spinal cord, spinal tumors, or mass lesions. Arachnoiditis (inflammation of the thin membrane just inside the dura membranc) can also create an abnormal spinal cavity, and cause a syrinx to develop.he most common area for a syrinx to develop is in the cervical spine (neck), with the second most common in the thoracic spine. As the syrinx grows in size, it may cause scoliosis (abnormal curve of the spine), which is best evaluated by special x-rays of the spine.
