What Vertebral Column?
Coccyx
not tradational pairs > remnants of normal vertebral features found elsewhere on the spine
Coccygeal Cornua: A pair of upward-projecting, horn-like processes on the first coccygeal segment. They articulate (connect) with a corresponding pair of cornua on the sacrum.
Transverse Processes: A pair of small, lateral bony projections on the sides of the first coccygeal segment.
Rudimentary Articular Processes: Small bumps found in pairs on either side of the posterior surface of the bone, representing unformed joint surfaces.
