3. DERMATOME: CUTANEOUS AREA RECEIVING ITS SENSORY INNERVATION FROM ONE SPINAL NERVE

4. SPINAL CORD SEGMENTS: CERVICAL THORACIC LUMBAR SACRAL COCCYGEAL CONUS MEDULLARIS

5. NOTE THE ARRANGEMENT OF GRAY AND WHITE MATTER AT DIFFERENT SPINAL CORD LEVELS 1. cervical spinal segments contain the largest number of fibers in the white matter 2. gray matter is maximal in the cervical and lumbar enlargements
