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)
Eight pairs of spinal nerves are located in the uppermost, cervical region of the cord: Twelve pairs are found in the thoracic region. Five pairs are in the lumbar area. Five pairs are in the sacral area. One pair is found in the most inferior, coccygeal region. Function These second order lower motor neurons, the spinal nerves, form part of the final common pathway for information traveling from the central nervous system to the periphery.
