The small bumps on the anterior sacrum that correlate with the transverse lines or fusion plates are called what?

The main idea here is recognizing the name for small bumps that mark the fused segments of the sacrum. The sacrum forms from five vertebrae that fuse over time, and on the front (anterior) surface you can see transverse lines where those boundaries lie. The tiny rounded bumps that sit at these junctions are called hillocks. They are the visible remnants of the sacrum’s segmented origin. Tubercules are general small rounded projections, cotyles are socket-like articular surfaces, and processes are more generic projections, so they don’t specifically describe these fusion-boundary bumps.
