What is the anatomical term commonly used for the backbone?

• A. Vertebrae
• B. Ligaments
• C. Muscles
• D. Cartilage

Answer: (A)

The backbone is made up of individual bones called vertebrae. Each vertebra is a single bone, and when stacked together they form the spine, also known as the vertebral column. So vertebrae is the most direct anatomical term for the backbone because it names the bones themselves that make up the structure. Ligaments connect vertebrae and help stabilize the spine, muscles move and support it, and cartilage provides cushioning in the joints and discs. These tissues are important around the spine, but they are not the backbone itself.
