Coccyx bone or tail bone 4

The coccyx, or tailbone, is both the smallest and the most inferior bone in the spinal column. It is a vestige of the caudal vertebrae found in the tails of most mammals. In the human body, the coccyx functions to anchor several muscles of the pelvic region and acts as one of the bones that bear the body’s weight while sitting.
