Extrait video c'est pas sorcier: les sorciers sont tombés sur un os

What are the bones used for? How do our joints handle shocks? What happens when you have a sprain or dislocation? How is the skeleton formed during fetal life? And during growth, how do the bones lengthen? What is scoliosis? When a bone breaks, how is it repaired? And why are the bones getting weaker with age? Sabine and Jamy discover the 206 bones of our skeleton. They explain everything about this frame that allows us to stand up and move.

C’est pas sorcier, the magazine of discovery and science. Broadcast on Wednesday, July 14, 2010. Find here the Youtube channel of C’est pas sorcier (in French)
