What can a dermatome map tell us about the location of a virus, such as the shingles?
What will be an ideal response?
The skin can be divided into different segments called dermatomes based on the spinal nerve that supplies the region with somatic sensation. Dermatomes can be combined and assembled into a dermatome map that represents all the spinal nerves (except the first cervical spinal nerve). The virus that causes the shingles can cause a painful skin rash with blisters. The virus can present unilaterally (along one side) along dermatomes. We can determine which spinal nerves are infected with the virus by the affected skin region(s).
