• A. Coccyx
• B. Pelvis
• C. Sacrum
• D. Lumbar

Answer: (A)

Identifying the tailbone’s name is about the end part of the vertebral column. The small bone at the base of the spine is the coccyx, commonly called the tailbone. It consists of fused coccygeal vertebrae and sits just below the sacrum, forming the very tip of the spinal column. It’s different from the pelvis, which is the ring of hip bones, and from the sacrum, the triangular bone above the coccyx formed by fused vertebrae, as well as from the lumbar region, which refers to the five lower back vertebrae. So the name you’re looking for is coccyx.
