All vertebrates have a vertebral column (i.e a backbone). This is the main feature.
The nerve cord is extremely delicate and can be damaged easily. To protect the nerve cord, it is enclosed in the vertebral column. The vertebral column is made up of vertebrae which are of distinct types but have a common feature of a central lumen through which the nerve cord passes.

notochord and vertebral column
The presence of homologous structures, such as the vertebral column in vertebrates, suggests the presence of a common ancestor. Learn more at 23andme.com.
No. "Backbone" is a common name for the spinal/vertebral column. Intervertebral disks are the the pieces of cartilage found between the individual vertebral bones in the column/backbone.

Vertebral column is also known as spinal column or backbone as it keeps the spinal cord protected. As cat and monkeys are also mammals, they share a common type of vertebral column as of human. However; the anatomy of the three is different hence the use of vertebral column also differs in them.
there are 312 to be exact, but the most common largest ones there are only 40
that is because humans and cows have many common features such as vertebral column same development in the nucleus
The most common disorders affecting the spine are degenerative, most often following trauma such as hard labour or whiplash. In spondylosis, bony spurs called osteophytes project from vertebrae and become denser, and vertebral disks degenerate and protrude. More commonly protrusion of a vertebral disk causes the spinal canal to narrow, distorts the local ligaments, and compresses an emerging nerve root, resulting in pain, weakness, and numbness in the area. Lumbar spinal stenosis is a condition characterized by the narrowing of a few segments of the spinal canal when the vertebrae, disks, and ligaments protrude, compressing the nerve roots
