The dermatome - An area of skin that is supplied with nerve fibres by a single spinal nerve from the cervical, thoracic, lumbar, or sacral regions of the spinal cord.
The entire body surface is an interlocking pattern of dermatomes, which is similar from one person to another. Abnormal sensation in a dermatome signifies damage to a particular nerve root, commonly due to a disc prolapse (“slipped” disc).
