How many pairs of spinal nerves are there in total?

Explanation:
Spinal nerves are paired nerves that emerge on each side of the spinal cord at every spinal segment, and counting all those pairs across the regions gives the total. There are eight cervical, twelve thoracic, five lumbar, five sacral, and one coccygeal pairs, which adds up to 31 in total. The cervical region has eight nerves even though there are seven cervical vertebrae because the C8 nerve exits below the seventh cervical vertebra, between C7 and T1. So when you include the cervical, thoracic, lumbar, sacral, and coccygeal pairs together, you get 31.
