Fun Bone Facts

  • Bony Babies: A person has more than 300 bones at birth and only 206 bones as an adult. Over time, small bones fuse together. 
  • First Aid: When broken or fractured a bone can actually repair itself. Casts help bones grow in the right direction.
  • Boning Up: Over a period of about seven years, each bone in our body is slowly replaced until it is a new bone.
  • Head Case: The bones in the skull fit together like a jigsaw puzzle. Sutured joints help to form a hard case that protects the brain and other sensory organs.
  • Busy Bones: Every second, our bone marrow produces two million red blood cells.
