We have 31 pairs of spinal nerves and they are named after the section of the spine they come out of. 8 pairs of cervical nerves (C1-C8) 12 pairs of thoracic nerves (T1 â T12) 5 pairs of lumbar nerves (L1-L5) 5 pairs of sacral nerves (S1-S5)
Overview. In order to categorize the spinal nerves, anatomists divide the vertebral column into four distinct areas, referred to as the cervical, thoracic, lumbar and sacral regions of the spine. Thirty-one pairs of nerves emerge from the spinal cord. Nerves that exit through openings between the vertebrae are called spinal nerves, while nerves that emerge through openings in the skull are known as cranial nerves.
