The spinal cord is surrounded by rings of bone called VERTABRAE.
These bones constitute the SPINAL COLUMN.
In general,the higher in the spinal column the injury occurs,the more dysfunction a person will experience.
The 8 vertabrae in the neck are called CERVICAL VERTABRA.
When cervical spinal cord injury occurs it USUALLY causes loss of function in the arms and legs,resulying in quadriparalysis.
Now,a person can "break their neck"yet not sustain a spinal cord injury if only the bones around the spinal cord(the vertabrae) are damaged,but the spinal cord is not affected.
In these situations the individual MAY NOT EXPERIENCE PARALYSIS AFTER THE BONES HAVE BEEN STABALIZED.
That is why one must NEVER be moved if a serious neck injury has occured.
