What is another name for the spinal column?

1. Vertebral column

2. Spinal cord

3. Backbone

4. Coccygeal chain

The correct answer is: Vertebral column

The spinal column is commonly referred to as the vertebral column. This term emphasizes the segmental structure of the spine, which is made up of individual bones called vertebrae stacked on top of each other. The vertebral column serves several critical functions, including providing structural support for the body, protecting the spinal cord, and allowing for flexibility and movement. While "backbone" is also a colloquial term for the spinal column, it is less technical than "vertebral column," which is preferred in anatomical terminology. The term "spinal cord," on the other hand, refers specifically to the bundle of nerves that runs through the spinal canal and is responsible for transmitting signals between the brain and the body, rather than the bony structure itself. Lastly, "coccygeal chain" is not a widely recognized term for the spinal column; rather, it specifically refers to the coccyx, or tailbone, which is the last part of the vertebral column. Thus, "vertebral column" is the most accurate and widely accepted term.
