Can someone answer this biopsychology question

I found this question on my review sheet related to dermatomes and I can't find a clear answer for it in my lecture notes or the book.

Different organ systems and muscle groups are enervated by different spinal nerves that enter and exit the spine at different levels. What implications does this have for predicting the prognosis for individuals with spinal cord injuries at different levels of the spinal cord?

The higher a spinal cord injury is, the more muscles and organ systems will be affected by the injury.
