What is "tail bone"?

The tailbone, also known as the coccyx, is located at the base of the spine. It consists of a small, triangular-shaped bone formed by several fused vertebrae. The tailbone serves as an attachment site for various ligaments and muscles, providing support and stability to the pelvic region. While it may not have a functional tail like some animals, the tailbone retains its evolutionary remnants. It also plays a role in weight distribution while sitting and serves as a point of attachment for certain pelvic floor muscles. Although small, the tailbone is significant for maintaining proper posture and contributing to overall spinal alignment and stability.
