Why do I have a skeleton?


Remove all your bones – along with the joints and muscles pinned to them – and you’d end up a shapeless, motionless bag of blood and organs. Your skull and spinal vertebrae, made of tough deposits of calcium and other minerals, are like armor for your brain  and nervous system. Special bone marrow in your vertebrae  and elsewhere is your body’s blood factory. Your muscles and joints, meanwhile, set your human machine in motion.
