All vertebrates have a vertebral column (i.e a backbone). This is the main feature.
notochord and vertebral column
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.
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
A compression fracture is common in the vertebral column, where the bone is crushed or collapsed due to excessive force or trauma. This type of fracture often occurs in individuals with osteoporosis or from high-energy accidents like falls from a height or car accidents. Treatment may involve pain management, bracing, and sometimes surgery to restore stability.

There are actually five characteristics that all vertebrates have in common; a vertebral column composed of multiple vertebrea (spine), a cranium (the bone that envelopes the brain), a closed circulatory system, nural crest, and a pronounced cephalization.
