Which term refers to the bones of the spine?

• A. Vertebrae
• B. Skeleton
• C. Ribs
• D. Pelvis

Answer: (A)

Vertebrae are the individual bones that make up the spine, forming the vertebral column. Each vertebra supports the body, protects the spinal cord, and provides attachment points for muscles. When you hear about the bones of the spine, you’re talking about these vertebrae as a group. The term skeleton refers to the entire framework of bones in the body, not just the spine; ribs are the bones of the rib cage, and pelvis is the set of hip bones at the base of the spine. So the bones of the spine are vertebrae.
