shoulder abduction and external rotation
an acute process in which the nucleus pulposus herniates through the posterior annulus, resulting in signs and symptoms of cord or nerve root compression is termed
soft-disk disease
In an injury involving the spinal cord, a transient loss of somatic and autonomic reflex activity below the level of neurological damage is called
spinal shock
