Question

Quizplus · Accepted Answer

The spinal cord is unable to repair itself in the same way that other tissues in the body can. When the spinal cord is damaged, the nerve fibers are often permanently destroyed or damaged so severely that they cannot communicate with other parts of the body anymore. Therefore, any functions controlled by those nerves cannot be regained.
