How do our bones stay together?
     Two kinds of connective tissue :
          Ligaments connect bones to other bones.
          Tendons connect bones to muscles.

How many bones do we have?
     When you were born, you had over 300 bones .
     They were very soft and were made mostly of cartilage.
     As you grow up, the cartilage hardens into bone and some bones grow together.
     By the time you are a full grown adult , you will have 206 bones.

Our skeleton is divided into two parts: the axial and appendicular sections.
The axial skeleton is made up of 80 bones.
     Skull
     Ribs
     Spine

The appendicular skeleton is made up of 126 bones
