Tailbone

Tailbone

• A. Calcaneus
• B. Coccyx
• C. Carpal Tunnel Syndrome
• D. Coloboma

Answer: (B)

The tailbone refers to the coccyx—the small bone at the very bottom of the spine. It sits beneath the sacrum and is typically formed by fused coccygeal vertebrae. The coccyx serves as an attachment point for pelvic floor muscles and ligaments and helps support a small amount of weight when seated. It is not the calcaneus (heel bone), nor related to carpal tunnel syndrome (nerve compression in the wrist) or coloboma (an eye defect).
