Can cervical spine root damage cause permanent paralysis in your entire body? from c1-c8? can a pinched nerve in this area cause full body paralysis?

Not really.: Spinal CORD runs from brain down spine encased in column of vertebral bones. Spinal NERVE exits between bones providing movement and sensation to a very specific body area. Damage to NERVE can produce loss of function and sensation only in a local area. Damage to CORD can produce loss of function and sensation below the level of the injury. Injury above C4 paralyses respiration - often fatal

Nerve root or cord?: Nerve root no, spinal cord yes a spinal cord injury at this level would spare arms but paralyze the rest including bowl and bladder and sensation if complete spinal cord injury a c8 nerve root injury would affect Just the triceps and hand intrinsic muscles
