To test the sensory fields, ask the patient to close their eyes, and then gently touch the soft end of a cotton-tipped applicator on random locations of the skin according to the dermatome region.

The spinal cord is divided into grey horns that house interneurons, autonomic neurons and somatic motor neurons as well as glial cells, and white columns that house ascending and descending tracts of axons. Spinal nerves originate from the spinal cord, carry both sensory and motor information and connect to the skin to form a map of dermatomes.
