3. Functions Protects Supports Provides (attachments – movement) Stores (minerals & energy) Produces

4. Protects… … the vital Organs -Ribcage surrounds the heart and lungs -Skull enclosed the Brain -Vertebrae surrounds the spinal cord

5. Supports… …and maintenance of posture. The skeleton provides a framework for the body & each part bears the weight of all structures. It also supports the softer tissues.

6. Provides … … attachment points for the muscles Muscles are connected to the bones via tendons. When muscles and tendons contract, they pull the bones causing movement at a specific joint.
