The wording of this question has me slightly confused, but my answer is this:
The bones that surround the spinal cord are the vertebrae. The spinal cord travels through the vertebral canal of each vertebra from the top of the skull (called foramen magnum) down the cervical, thoracic, and part of the lumbar spine where if forms the conus medularis. This is where the spinal cord 'stops' (around L1/L2) and becomes the caudal equina (horse tail). Cauda equina is a small bundle of nerve fibers that branch out and leave at various levels of the spine from L2 all the way down to the sacral formina.
Let me know if this is not what you were looking for.
