  • The sacrum and coccyx

    The fused bones at the base of the column. The sacrum carries the weight of the trunk into the pelvis and lets the sacral nerves out through its foramina; the coccyx is the tailbone.

  • The vertebral column

    The flexible stack of bones that carries the head and trunk, protects the spinal cord and lets the back move. Its five regions, its four curves and the parts every vertebra shares.
