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)
Depending on definition in humans there are twelve or thirteen cranial nerves pairs, which are assigned Roman numerals IâXII, sometimes also including cranial nerve zero. The numbering of the spinal nerves is based on the order in which they emerge from the brain, front to back (brainstem).nd, as noted, earlier there is reason to consider both the olfactory (I) and Optic (II) nerves to be brain tracts, rather than cranial nerves. Further, the very small terminal nerve (nerve N or O) exists in humans but may not be functional.
