Part of the spine (on left) shows how nerve roots connect to the spinal cord. The most serious types of nerve injuries are an avulsion (A), where the nerve roots are torn away from the spinal cord, and rupture (C), where the nerve is torn into two pieces. A less serious injury is stretching (B) of the nerve fibers.
