Content and assessment criteria
Structure:
• Bone structure
• Axial and appendicular skeleton

• Location of major bones
Functions:
• Support; protection; attachment; movement; cell production (red blood cells); storage
(minerals).
Types of joints:
• Synarthrosis (fixed, fibrous)

The skeleton
What do you know about the skeleton?
• The framework that gives the body structure
• 206 bones
• Bones connect to form joints
• Ligaments connect bone to bone
• Cartilage covers the end of the bones
• Tendons attach muscle to bone
Functions of the skeleton
• Support - a bony support framework
• Attachment - muscles, tendons and ligaments.
• Movement - bones act as levers and muscles pull on bones
• Production - red and white blood cells
, • Protection – different structures protect vital organs
• Storage - minerals, e.g. calcium
