What is also called the spinal column, backbone, or spine, that forms the axial skeleton and runs from skull to pelvis?

• A. Spinal cord
• B. Vertebral column
• C. Skeleton
• D. Backbone

Answer: (D)

The backbone is the long bony axis of the skeleton that forms the spinal column. It runs from the base of the skull down to the pelvis and is made up of vertebrae stacked in a column. This structure is part of the axial skeleton, providing support and protecting the spinal cord that lies within the surrounding vertebral canal. Among the terms given, backbone is the everyday name for the spinal column, matching the description of a central, bony axis from skull to pelvis. The spinal cord refers to the nervous tissue inside it, not the bone; the vertebral column is the bones themselves, and the skeleton is the entire framework of the body, not just this central axis.
