The nerves from the spinal chord supply sensation (for example, pain, touch, temperature) to the body. Each nerve supplies sensation to a specific area as noted in the diagram above. The different segments of the spinal cord are as follows:

• Cervical (neck and arms): 8 nerves, C2-C8 (note that C1 has no sensory distribution)
  
  
• Thoracic (arms, upper/mid back): 12 nerves, T1-T12
  
  
• Lumbar (lower back, legs): 5 nerves, L1-L5
  
  
• Sacrum (buttock area, legs): 5 nerves, S1-S5
