Spinal vertebra are called just that. There are subdivisions: cervical (neck), thoracic (chest), and lumbar (lower back). There are two sets that have fused in the adult: the sacrum and the coccyx (tail bones).

The spinal cord is protected by the vertebrae.
Vertebrae
There isextension of brain in neck, thorax and abdomen in what is called as vertebral column. You have seven cervical vertebrae, twelve thoracic vertebrae and five lumber vertebrae fallowed by sacrum.In between them, you have inter-vertebral disc and various ligaments. Which keep them in position. In the hollow part of these vertebrae, there is spinal cord. It extends to the lower border of second lumber vertebrae. Down to it, there is bundle of nerves called as cauda-equina.
The spinal cord is protected by the vertebral column or spinal column. The vertebral column is a collection of individual bones called vertebrae that encase and protect the spinal cord. The vertebral column is divided into three parts: seven cervical (neck) vertebrae at the top, twelve thoracic vertebrae in the midback, and five lumbar vertebrae in the lower back. Below the lumbar vertebrae, but not protecting the spinal cord, are the sacrum and coccyx (tailbone).
nerve plexusesThe spinal nerves emerge from the spinal cord at the brain stem, and between each vertebrae.
The spinal cord
No one bone protects the spinal cord. The spine consists of 33 bones called vertebrae, of which the spinal cord travels through the center. These vertebrae are held in place, or supported, by ligaments and muscles. Cushions between each vertebrae are called discs. So, essentially, the spinal cord is protected by bone, discs, ligaments and the muscles.

The vertebral column usually consists of 33 vertebrae: 24presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae).
