What is the spinal column called?
Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.
What is the difference between spine and spinal cord?
A column of bones called vertebrae make up the spine (spinal column). The vertebrae protect the spinal cord, a long, fragile structure contained in the spinal canal, which runs through the center of the spine.
What bones are part of the spinal column?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
What are the names of the spinal vertebrae?
Vertebral Column
Term | # of Vertebrae | Abbreviation |
---|---|---|
Cervical | 7 | C1 – C7 |
Thoracic | 12 | T1 – T12 |

What is difference between backbone and spinal column?
Spinal Cord is the tube-like structure which consists of bundles of nerve fibers. It is covered by the meninges and is surrounded by the cerebrospinal fluid. Backbone or the spinal column is the central axis of the skeleton in all vertebrates. In a newborn human, there are about 33 bones that make up the spinal column.

How many bones are in the spinal column?
The average person is born with 33 individual bones (the vertebrae) that interact and connect with each other through flexible joints called facets.
How many vertebrae does the vertebral column have?
The average person is born with 33 individual bones (the vertebrae) that interact and connect with each other through flexible joints called facets. By the time a person becomes an adult most have only 24 vertebrae because some vertebrae at the bottom end of the spine fuse together during normal growth and development.
