The bones in your arm, forearm, leg, hands, and feet
are easily felt. The adult skeleton has 206 bones, but we are actually
born with more than that. Bones are living tissue, that grow with your
body. Bones are composed of calcium phosphate (CaPO3). They
take nutrients from your blood to help build your skeletal frame. The
claim that milk makes strong bones, refers to the increased amount of
calcium ions (Ca+) available for bone formation. When you are
born there are several bones that eventually become connected as you
grow older. A good example of this is the skull. The skull
protects the brain and is made of smaller bony sections that fuse
together as we grow older. If you feel a baby’s head after birth the
divisions between the bones can be felt.
