The coccyx is formed by how many fused vertebrae?

Explanation:
The coccyx is formed by fusion of coccygeal vertebrae. In adults, the tailbone is typically made from four coccygeal vertebrae that fuse into a single bone. At birth there are separate segments, and they fuse as you grow, giving a compact structure for support at the very end of the spine. There is natural variation—some people may have three or five fused segments—but four fused vertebrae is the most common configuration encountered.
