Detailed explanation-1: -The nerves coming from the spinal cord are called the spinal nerves. There are 31 pairs of spinal nerves coming from the spinal cord and spread on either side of the vertebral column. They are classified into cervical, thoracic, lumbar, sacral, and coccygeal nerves.

Detailed explanation-2: -At the bottom of the spinal cord (conus medullaris) is the cauda equina, a collection of nerves that derives its name from the Latin translation of “horse’s tail” (early anatomists thought the collection of nerves resembled a horse’s tail).

Detailed explanation-3: -The vertebral canal is composed of the vertebral foramen located in the cervical, thoracic, and lumbar vertebrae. The vertebral or spinal cord typically ends at the level of the L2 vertebra, where the spinal cord gives off multiple branching spinal nerves and nerve rootlets known as the cauda equina.

Detailed explanation-4: -The spinal cord is a major part of the central nervous system which comprises tubular nerve bundle while the vertebral column is a bony, segmented structure which supports head and thorax. The spinal cord runs inside the vertebral column, and vertebral column protects the spinal cord.
