The skeleton

An adult skeleton usually has 206 named bones, held together at joints that bend, turn and swivel. Pick bones in the 3D skeleton, watch a ball-and-socket, a hinge and a pivot joint move, and learn how bones grow and mend. This course is general information about the body, not medical advice; for an injury or a question about your own bones, see a health professional.
