.jpg) Primary Science Learning Experience PS–42 Skelley – The Real Human Skeleton  WHAT IS HAPPENING When Skelley was born, he had ~300 bones. As he grew, many bones fused together. You now see him with only 206 bones. Bones support our bodies, allow muscles attachment and movement. Bones hold calcium and store vital minerals. Marrow in the bones makes blood cells. Our longest adult bone is the femur (thigh bone). The smallest bone is the stirrup bone in our ear. Our marvellous hand comprises 26 bones. Bones are connected to other bones at various joints: fixed joints (eg skull), hinged joints (eg fingers, toes), ball-socket joints (eg shoulders, hips). Male and female skeletons are slightly different: slightly thicker, longer legs and arms for males; wider pelvis for females (for pregnancy and childbirth).
