Which part of the vertebral column has one more pair of nerves coming from it than it has vertebra?

The cervical region of the vertebral column has one more pair of nerves than vertebrae. There are seven cervical vertebrae (C1 to C7) but eight pairs of cervical nerves (C1 to C8). This occurs because the first pair of cervical nerves exits above the first cervical vertebra, while the remaining pairs exit below their corresponding vertebrae.
