What are we goin to learn today?
Today we are going to learn:
Why it is important that bones are jointed together.
What kind of joints there are.
How freely movable joints work.
Slide 2 - Diapositive
Joints
Joints are responsible for 2 main purposes of the skeleton: making you a solid being and making you move. There are different kinds of joints. Characterized by their build and ability to move.
Slide 3 - Diapositive
