Which bone is commonly called the tail bone?

Explanation:
The tail bone is the coccyx, the small bone at the very end of the vertebral column. It sits beneath the sacrum and is formed by 3–5 fused coccygeal vertebrae, a remnant of a tail from our distant ancestors. The sacrum is the larger bone just above it, part of the pelvic base. The mandible and maxilla are facial bones—the jaw—not at the end of the spine.
