These are grouped into the corresponding cervical, thoracic, lumbar, sacral and coccygeal regions of the spine. There are eight pairs of cervical nerves, twelve pairs of thoracic nerves, five pairs of lumbar nerves, five pairs of sacral nerves, and one pair of coccygeal nerves. The spinal nerves are part of the peripheral nervous system.
The sacral canal is the caudal continuation of the lumbar spinal canal. The contents of the sacral canal include the meninges, the lower portion of the cauda equina (sacral and coccygeal nerve roots), the filum terminale, and fibrous and fatty tissue (Fig 3) (4). The epidural space terminates at the sacral hiatus.
