Internal to this peripheral region is the grey matter, which contains the nerve cell bodies arranged in the three grey columns that give the region its butterfly-shape. The dorsal roots are afferent fascicles, receiving sensory information from the skin, muscles, and visceral organs to be relayed to the brain. Nonoperatively treated patients tended to require more health care, including pain medication, magnetic resonance imaging scans, and physical therapy.
