Full Spinal Cord Description
[Continued from above] . . . of lumbar nerves (L1 - L5), five pairs of sacral nerves (S1 - S5), and one pair of coccygeal nerves. The nerves coming from the upper part of the spinal cord pass outward nearly horizontally, while those from the lower regions descend at sharp angles. This is derived from the consequence of growth. In early life, the spinal cord extends the entire length of the vertebral column, but with age, the column grows faster than the cord. As a result, the adult spinal cord ends at the level between the first and second lumbar vertebrae, so the lumbar, sacral, and coccygeal nerves descend to their exits beyond the end of the cord.
