      You bones don’t actually make the movements. Your brain communicates with the muscles in your body through the nervous system. Messages are sent by the brain to the muscles through the nerves to make the muscles move. The muscles are attached to the bones with tendons so when the muscles move that causes the bones to move.

      A great answer from Miranda and exactly what I would have written. It is a great marvel of our bodies’ design that we can move without really having to think about it. This is one thing some scientists are looking at, so that they can create new prosthetic limbs that peope can control with their minds – like our natural limbs. They are getting a lot closer, but it is still very hard work to use these types of limbs, because although the connection is there to the mind, the individuals’ have to think very hard to get them to do what they want.
