The next slide shows the outline of a human skeleton and a
cluster of some bones.
Your task is to try to identify where each bone fits into the
skeleton.
When you click on each bone, it will move into its correct
position.
Once you have placed them all, try and identify the names
of each bone on the final slide.

MOVEMENT
-Two bones next to each other can form a
flexible joint. The bones in a flexible joint
are moved by muscles which are attached
to the bones by tendons.
-Ligaments hold the bones in a flexible join
together. The ends of bones in a flexible
joint are often covered in a slippery tissue
called cartilage, which helps them slide
past each other.
